Carrier heating in a Terahertz Optical Asymmetric Demultiplexer

Not Accessible

Your library or personal account may give you access

Abstract

We report interferometric switching experiments with an InGaAs semiconductor optical amplifier (SOA). Measured switching windows reveal ultrafast refractive index changes attributed to carrier heating. This conclusion is supported by calculations using a phenomenological model.
