Passband flattening in waveguide grating devices

Jian-Jun He; Emil S Koteles; Bedwyr Humphreys

A new passband flattening technique for waveguide grating devices is proposed and experimentally verified. It uses phase modification of grating elements to flatten and steepen the passband shape while maintaining single mode input and output waveguides.
