Diffusive transverse coupling between adjacent InSb transphasor channels.
The proportionality of a transphasor signal to the photoexcited carrier density has been utilized to measure the transfer of the signal between adjacent optical channels and to estimate practical transphasor packing densities (~10(3) cm(-2)) for a pure, bulk étalon of InSb, 280 microm thick. By using the transphasor as a probe of the carrier population distribution produced by an adjacent beam, the ambipolar diffusion length was measured as 74 microm.
