Paper Abstract
We propose a novel 6-port planar waveguide coupler device for adding and/or dropping tow different wavelengths from a WDM channel using a single grating. By writing a blazed Bragg grating into a few-moded core at a slight angle to the waveguide propagation direction, power can be coupled from the fundamental mode into higher-order, backward-propagating modes and vice-versa. Each such mode is channelled into a particular output port using an adiabatic splitter. Modeling results indicate that more than 99.99 percent of the power in the fundamental mode can be coupled into the higher-order modes at their respective Bragg wavelengths.
