Outline of Final Research Achievements

We proposed a monolithic PLC-based 3-mode DEMUX.　We qualitatively described the wavelength dependence and numerically investigated the wavelength dependent insertion loss of the DEMUX. It showed an insertion loss less than 1 dB and a wavelength dependent loss of less than 0.5 dB for all of the 3 modes in C band.
By cascading two DEMUXes of different center wavelengths and numerically investigated mode separation characteristics. This simple design enhances wavelength dependence and may extend the fabrication tolerance of the mode DEMUX.
