Abstract
We show how polarization-independent optical wavelength filters can be achieved using asymmetric directional couplers with birefringence-compensation. Simulations demonstrate that excellent polarization behavior can be achieved with practical tolerances and without sacrificing filter bandwidth or insertion loss.Keywords
