Abstract

Wavelength demultiplexers, based on the two-mode interference principle, are demonstrated for the first time in the InGaAlAs/InP material system. In this paper theoretical modelling, device fabrication and experimental results are discussed. Wavelength separations between 35 and 100 nm have been achieved in the spectral range of 1.3-1.6 μm with channel isolation as high as 17 dB for unpolarized light.
