Abstract :
We present a new type of wavelength demultiplexers based on a Bragg reflector waveguide amplifier, which provides a large angular dispersion of 1~2°/nm. Benefiting from its large steering and sharp divergence angles, we record a number of resolution-points over 200 for 1mm long devices, which is the highest number in similar devices ever reported.
