SC442 - Free Space Switching Systems: PXC and WSS

Monday, 12 March
09:00 - 12:00

Short Course Level: Advanced Beginner


David Neilson; Nokia Bell Labs, USA

Short Course Description:

This course will provide an overview of photonic cross connects (PXC) and wavelength selective switches (WSS), how they work and what the design trade offs are. The requirements and performance for theses switching subsystem will be reviewed. The course will explain the fundamentals optical schemes for these switches and how those can be translated into practical optical designs. An overview of the basic requirements and capabilities of the switching technologies MEMS, LCOS and others used in these systems will be given. Other critical technologies including polarization, gratings and lens and fiber arrays will be discussed. The testing of subsystem and the interpretation of the data analysis will be reviewed.  Recent results and alternative approaches form the research community will be discussed.

Short Course Benefits:

This course will enable you to:

• Identify key capablities and performance metrics of optical switching systems.

• Understand the basic design constraits of free space optical switches.

• Identify and understand the various component technologies that are used to construct these switches.

• Get an insight into future trends in research and product commercialization of optical switching systems.

Short Course Audience:

This advanced-beginner course is intended for a diverse audience including lightwave system and sub system researchers and engineers. Some basic knowledge of classical optics such as lenses, gratings and polarization optics will help in better understanding the course but is not a prerequisite.

Instructor Biography:

David T. Neilson is Technical Manager, Hybrid Integrated Devices Research at Bell Labs, Nokia, Holmdel. David received his B.Sc. And PhD degrees in Physics from Heriot-Watt University U.K. in 1990 and 1993 respectively. His doctoral thesis was on ‘Optical Nonlinearities and Switching in InGaAs Quantum Wells’. From 1993 to 1996 he remained at Heriot-Watt as a post-doctoral researcher working on free-space optical interconnect and switching systems. From 1996 to 1998 he was a Visiting Scientist at NEC Research, Princeton NJ, researching optical interconnects for high performance computing systems. He joined Bell-Labs in 1998 where he has researched several optical switching systems and technologies including using micro-mechanical elements and LCoS for wavelength selective switches and optical crossconnect. He has also led groups working on InP optoelectronic growth and fabrication.  He has authored over 100 publications and over 20 patents on both devices and systems in the field of optical interconnects and switching. He has been on several IEEE-LEOS, OSA, and SPIE conference programs in the field of optical interconnects and switching.  He is a Fellow of IEEE.
