Paper Abstract

After the arm width of an asymmetric Mach-Zehnder interferometer is used to adjust the phase delay at the end, a three-wavelength demultiplexer can be made by cascading two such interferometers. Three wavelengths, 0.98 micrometers , 1.31 micrometers , and 1.55 micrometers are taken as an example. The device is about 1.5 cm long and demonstrated high extinction ratios for all three wavelengths by BPM simulations.
