Paper Abstract

The implementation of a low-loss demultiplexer with a KRS-5 grism structure for a dense wavelength division demultiplexing (DWDDM) system in fiber communication is carried out. The system has 16 channels with wavelength spacing of 0.8 nm in the C-band wavelength region. This device is successfully fabricated by a precise plunge-cut diamond-turning technology. Numerical calculations and measurements indicate that this DWDDM is polarization independent and has higher optical efficiency and signal to noise ratio (SNR).
