Abstract

We theoretically demonstrate the viability of parallel anti-symmetric waveguide Bragg gratings within a two-mode waveguide. These gratings produce reflections with mode conversions. This is the functional equivalent of superimposed Bragg gratings in silica-on-silicon without requiring multilevel etches. Also, due to their weaker coupling constant, these gratings allow for devices with narrow spectral full-width at half-maximum that can process multiple wavelength channels for applications such as optical add-drop multiplexers and optical encoders in optical communication systems.
