Efficient coupling to W1 photonic crystal waveguide on InP membrane through suspended access guides

2008 
Suspended access ridges have been designed and integrated with a single-missing row photonic crystal guide on InP membrane in order to improve the coupling efficiency. This integration provides control of the injection into the photonic crystal (PhC) guide and a deterministic choice of the termination of the PhC. Low propagation losses have been measured for both the photonic crystal guide on InP membrane and the suspended ridges.
