Performance of Bragg grating assisted multi-band add-drop filters on the silicon-on-insulator platform.

Abstract

In this work, we designed multi-band add-drop filters based on Bragg grating assisted Mach-Zehnder interferometers for the LAN wavelength division multiplexing standard. We experimentally assessed their behaviors on the silicon-on-insulator commercial platform. We experimentally report insertion losses of less than 1 dB and a mean interchannel crosstalk of -20 dB for a channel separation of 9 nm and a channel width of 3 nm
