Abstract
A high-contrast, three port optical AND gate based on the
photoconductive effect in Ga0.47In0.53As:Fe and
operating in the λ=1.3-5 μm wavelength range is demonstrated.
A 250:1 optical power contrast ratio (or 48 dB in electrical power after
detection) is obtained in an optical-to-optical time division
demultiplexing of a 100 MHz pulse train by a 6.25 MHz clock, both at
λ=1.3 μm, with the demultiplexed output pulses at λ=1.5
μm
