  • High index-contrast photonic devices and applications thereof
    Patent number: 10324031
    Abstract: A photonic processing module (100) comprises a high index-contrast waveguide device comprising a substrate (102), a first layer (104) disposed on the substrate having a first refractive index, and a relatively thin second layer (106) disposed on the first layer. The second layer has a second refractive index providing a high index-contrast with the first layer, and the device includes at least one thin-ridge waveguide element (108) formed in the second layer which supports a guided mode in a longitudinal direction. An optical input port (110) is configured to direct an input beam into a slab mode of the second layer, the beam being directed to propagate at a predetermined angle ? to the longitudinal direction of the thin-ridge waveguide element. The angle ? is associated with a resonant coupling between the slab mode of the second layer and the guided mode of the thin-ridge waveguide element.
