We present a new type of wavelength demultiplexers based on a Bragg reflector waveguide, which provides a large angular dispersion of 1~2°/nm. Benefiting from its large steering bandwidth and sharp divergence angles, we record a number of resolution-points (possible channel-count in demultiplexing) over 200 and 1,000 for active-type and passive-type devices, respectively. It is the highest number in various multiplexing elements ever reported. The device size is as small as a few millimeters.
