Abstract :
A novel coupler-type demultiplexer fabricated by K+-ion exchange in soda-lime glass and applicable to three wavelengths with arbitrary wavelength spans is described. The output light-power extinction ratios of about -20 dB were measured for the operation wavelengths of 1.152, 1.310, and 1.523 μm. A simple method of designing for the structure parameters is also presented
