Distributed etched diffraction grating demultiplexer with engineered response

We show that it is possible to significantly reduce the side lobe level and the noise floor of the etched grating demultiplexer by as much as 20 dB and 19 dB respectively by apodizing the reflection response. This is possible because the tasks of dispersion and reflection are separated in these devi...

Summary:We show that it is possible to significantly reduce the side lobe level and the noise floor of the etched grating demultiplexer by as much as 20 dB and 19 dB respectively by apodizing the reflection response. This is possible because the tasks of dispersion and reflection are separated in these devices.
