Towards tunable telecoms lasers using Stabilised Fabry-Perot quantum well lasers.

Date Tuesday, 17 October 2006

Time 4.00pm

Room Main Conference Room, Tyndall

Abstract

We have achieved single mode operation and multichannel operation using Fabry -Perot lasers with modal perturbations. Lasers are single mode and can be tuned in 400 GHz steps, making them promising for next-generation applications such as coherent wavelength division multiplexing. Channel spacing can be specified via photolithography and devices are monolithic with no overgrowth needed.
