Apodizable Integrated Filters for Coarse WDM and FTTH-Type Applications

Abstract

A dual-channel integrated multiplexer, based on holographic Bragg reflector (HBR) devices and exhibiting flat-top, 4-nm-wide channels is demonstrated. Theory calibrated by the achieved performance indicates that HBR waveguide grating devices can be implemented to provide fully integrated and high-performance multiplexer solutions for CWDM and FTTH applications.
