OSuB — Silicon Photonics Integrated Devices
Organizers: Haifeng Li; Tyco Telecommunications, USA.
Category 4. Switching, Wavelength-Selective Filtering and Routing Devices — Room 6B
Silicon Photonics, the technology of using standard silicon and CMOS manufacturing techniques to make optical devices, has become a reality with the current achievements in both the academic research and industrial development. With the high index contrast of SOI structure, silicon photonic devices can be made more than 10 times smaller than its conventional silica counterparts. By making the silicon photonic devices on top of CMOS circuits, the photonic devices can be seamlessly integrated with electronic driving circuit to achieve higher level of integration to further reduce the interconnection and packaging cost and improve operating speed. This workshop will focus on two general categories: 1) what can silicon photonics technology do? To explore new device structures and functions being realized by this technology, and 2) how can silicon photonics do it? To discuss the practical aspects of the technology, such as input/output coupling, and polarization diversity, etc.

Organizers: Jane M. Simmons¹, Dion Leung², Claus Gruber³, Dominic Schupke³; ¹Monarch Network Architects, USA, ²Tellabs, USA, ³Nokia Siemens Networks, Germany.
Category 9. Networks — Room 6D
Optical networks have grown in size and complexity to the extent that design tools are an integral part of the design process. This is especially true for network designs based on optical-bypass technology and designs requiring optimization across multiple layers. This workshop will examine the current state of optical network design tools from several perspectives. Carriers will discuss what they look for in a design tool and how tools can be improved to meet their needs. System vendors and design-tool developers will discuss the major challenges of, and their approach to, developing algorithms to optimize transparent and multilayer networks. This will include a discussion of techniques that are a departure from traditional design methodologies. The speakers’ presentations will be followed by a panel discussion.

OSuD — Optical Versus Electronic Techniques for Distortion Compensation
Organizer: Peter Winzer; Alcatel Lucent Bell Labs, USA.
Category 3. Signal Measurement, Distortion Compensation Devices and Sensors — Room 6E
Recent developments in high-speed digital signal processing hardware have enabled powerful electronic impairment mitigation engines, such as 10-Gb/s maximum likelihood sequence estimation, 10-Gbaud electronic pre-distortion, and coherent detection with digital phase locking. In contrast to optical impairment mitigation techniques, which can simultaneously operate on multiple WDM channels and which can be distributed throughout the network in order to optimize fiber transmission performance, electronic techniques inherently work as lumped transponder elements and on a per-channel basis. This workshop will discuss the evolution of optical and electronic impairment mitigation methods and devices as well as their advantages and shortcomings in the light of optically-routed transport networks.
OSuE — The Roles of Electronics and Photonics in Signal Processing
Organizers: Rodney S. Tucker¹, Djan Khoe², David Miller³; ¹Univ. of Melbourne, Australia, ²Technical Univ. of Eindhoven, Netherlands, ³Stanford Univ., USA.
Category 8. Optical Processing and Analog Subsystems — Room 6F
The processing power of digital electronic circuits continues grow according to Moore’s law. But to maintain this growth, electronic chip designers are struggling against thermal limitations caused by energy dissipation in the devices and in interconnects between devices. The ultra-high bandwidth of optics, and the high switching speed in photonics devices based on nonlinear optics suggests that digital optical devices may eventually replace electronics in very high speed signal processing, especially in applications where the data to be processed is already in optical form. This workshop will explore the underlying issues that will determine the future roles of electronics and photonics in digital signal processing. Topics to be covered include power and energy considerations in electronics and photonics, processing speed, device integration issues, and intra-chip and inter-chip interconnects.
OSuF — Extended Reach PON and Central Office By-Pass
Organizer: Russell Dave; British Telecom, UK.
Category 10. Access Solutions, Demonstrations and Non-Telecom Applications — Room 7
FTTP is becoming a mainstream access technology, typified by large GEPON deployments in the Far East and BPON/GPON deployments in the USA. In Europe FTTP is largely confined to municipality and local initiatives with incumbent operators confining themselves mainly to new build/niche markets where FTTP is economically attractive. For FTTP to be viable as a mass-market replacement for xDSL both the capital expenditure and the operational cost of the complete end to end network must be reduced. Extending access network reach, bypassing Central Offices and Metro transmission networks, has become a topic of growing interest in the last few years. This workshop explores the latest thinking on Long Reach Access, its potential for cost reduction and progress towards realising commercially viable standards based solutions.
Extending the reach of PONs has been a research topic for some years and is now getting close to commercial application. In this workshop four major operators from around the worldwide will describe network applications and technical progress to date. Three vendors will then describe progress towards commercial products. Finally a major university will review technology challenges and compare architectures.

NSuA — Packet/TDM Network Convergence: Opportunities and Challenges
Organizer: Bob Doverspike; AT&T Labs Res., USA.
NFOEC A. Optical Networks and Services — Room 8
Today by encapsulating packets into TDM payloads, links of packet networks are transported via TDM circuits and thus create “overlay networks” over the legacy SONET/SDH layer. In contrast, Ethernet is emerging as the preferred physical layer technology in the enterprise market and residential video network. However, TDM Private Lines (DS1 through OC-N) continue to be transported via SONET/SDH. Does Ethernet result in yet another overlay network or is there a simpler “converged” vision at the end of the tunnel that will transport all services? Will the converged network be Ethernet, WDM, or a hybrid? How will TDM Private Lines be transported over the converged network and what is the fate of the legacy TDM layer? This workshop will assemble top experts in the field to help answer these questions.

Finally, the third session will consider the emerging applications in high speed optical communication systems and will attempt to establish a roadmap that connects the materials and platforms discussed in the earlier sessions with the applications, examples being optical regeneration, wave-length conversion, optical performance monitoring, optical switching and routing and optical logic.
OME — Can Optical Packet Switching Solve the Bottleneck Problem in Electronic Routers?
Organizers: Ken Ichi Kitayama¹, Keren Bergman²; ¹Osaka Univ., Japan, ²Columbia Univ., USA.
Category 7. Transmission Subsystems and Network Elements — Room 6F
There are growing concerns that throughput bottlenecks and the ever-increasing power consumption/footprint in electronic routers will eventually limit network capacity. Optical packet switching (OPS), in which optical packets are buffered and forwarded in optical form, and optical burst switching (OBS), in which buffers are completely eliminated, may provide solutions to this “electronic bottleneck.” This workshop will feature invited talks from different sectors to present views on outstanding issues in OPS and OBS, including; (i) capabilities, limitations, and future prospects of electronic routers, (ii) how far optical technologies such as optical interconnects, optical switching, and optical buffering can penetrate into electronic router architectures, (iii) new approaches to optical buffering, and (iv) whether OPS and OBS can be scaled up to realistic sizes.
OMF — Device Requirements for Advanced Modulation Formats
Organizers: Charles Joyner¹, Paul Morton²; ¹Infinera, USA, ²Morton Photonics, USA.

Advanced modulation formats provide increased communication capacity and transmission distance, and are increasingly being used in experimental and deployed systems. This workshop will investigate methods for encoding and decoding data with amplitude, phase, and frequency; comparing maximum data rate, overall capacity and transmission distance. Candidates for comparison include: RZ, NRZ, duo-binary, DQPSK, PM-QPSK and coherent transmission. Systems expert speakers are encouraged to choose and defend methods that have the highest theoretical information capacity x distance product, with a practical implementation strategy. Device designers will speak on the relative difficulties of producing the more complex transmitters and receivers required for these advanced modulation formats. Following presentations, a panel discussion will highlight tradeoffs between performance, complexity and overall system cost for the various modulation formats.
