The optical properties of two hybrid silicon taper designs are investigated. These tapers convert the optical mode from a silicon waveguide to a hybrid silicon III/V waveguide. A passive chip was fabricated with an epitaxial layer similar to those used in hybrid silicon lasers. To separate optical scattering and mode mismatch from quantum-well absorption, the active layer in this paper was designed...
We demonstrate a Si3N4 waveguide optical resonator with a record high quality factor of 55 million using planar waveguide couplers. Investigations into coupler losses are studied to further increase performance.
A novel ring resonator based 1×16 optical power splitter is demonstrated on Si3N4 waveguides with excellent uniformity (0.4dB) and low excess loss (0.9dB). The device is promising for high port count splitters without cascading.
Two types of hybrid silicon tapers are studied. Single taper loss is 0.3 – 0.5 dB, enabling integration of III/V actives on silicon-on-insulator passive circuitry with low loss. Keywords-Hybrid integration, silicon-on-insulator technology
We characterize an approach to make compact low loss silica on silicon waveguides and achieve good agreement with theory. Record low losses of 8 dB/m for 0.5-mm bend radius down to 3 dB/m for 2-mm bend radius were achieved.
