title: GaAs/AlGaAs integrated-optic wavelength demultiplexer.
abstract: An integrated-optic dual-channel wavelength (de)multiplexer is demonstrated on a GaAs/AlGaAs heterostructure. The device, an asymmetric Mach-Zehnder interferometer, operates with a channel separation of 19 nm in the 1500-nm-wavelength range.
