Abstract
Experimental results of a demultiplexer using an aberration corrected concave grating for an optical system are described. The demultiplexer has 10 channels and a wavelength spacing of 20 mm from 0.7 to 0.9 μm wavelengths. Insertion losses and crosstalk were less than 2.5 dB and -30 dB, respectively, for all channels.Keywords
