Abstract

The reduction of the carrier lifetime in the waveguide is a requisite for the application of ultra-high speed optical communication and signal processing. A reduced carrier lifetime of less than 70 ps can be obtained by stimulated recombination utilizing continuous wave assist light. Further reduction can be expected for shorter devices. This mechanism can be used for ultra-high repetition-rate gate function and noise reduction function because of less heat generated through this fast stimulated emission.
