David Neilson

Murray Hill, NJ, USA

Research Interests



Dr David Neilson is Group Leader of the Optical Transmission Group of Nokia Bell Labs. He has been with Bell Laboratories in Holmdel NJ since 1998, where he conducted research on MEMS based switches and compensators, highly integrated InP based optoelectronic components and subsystems, the role of optical interconnects and switching for high capacity optical switches and routers and the energy consumption of networks.

Prior to joining Bell labs he was a Visiting Scientist at NEC Research Institute,Princeton, NJ, researching optical interconnects for high-performance computing.

He has over 150 publications and 37 issued patents in the field of optical interconnects, switching and optoelectronic devices. Dr. Neilson is a Bell Labs Fellow and Fellow of IEEE.


  • 1990     B.Sc. with 1st Class Honours in Physics, Heriot-Watt University, UK.
  • 1993     Ph.D. in Physics, Heriot-Watt University, UK. Thesis titled ‘Optical Nonlinearities and Switching in InGaAs Quantum Wells’. This work was in collaboration with and partly supported by BT Laboratories, Ipswich, UK.
