Distributed Etched Diffraction Grating Demultiplexer With Flat-Top Insertion Loss Envelope

Distributed Etched Diffraction Grating Demultiplexer With Flat-Top Insertion Loss Envelope

It is numerically shown that incorporation of a distributed Bragg reflector at the facets of an etched diffraction grating (EDG) can be used to tailor the output spectral response of the device. This technique is used to optimize the overall insertion loss envelope of a distributed etched diffractio...
