We show that it is possible to obtain 2?? 2 waveguide couplers with arbitrary power splitting
ratios by interconnecting a pair of unequalwidth waveguides as the phase-tuning section …

Waveguide crossings with different small crossing angles were simulated and
experimentally investigated on a silica-on-silicon platform. To achieve low crosstalk, a …

A waveguide crossing based on multi-mode interference is designed and experimentally
characterized on the silicon platform. The insertion loss of the device is measured as 43±4 …

An intra-chip coupling scheme from optical fibers to silicon strip waveguides is
demonstrated. The couplers consist of silicon inverse width tapers embedded within silicon …

For Si wire waveguides, we designed a highly efficient fiber coupling structure consisting of
a Si inverted taper waveguide and a CMOS-compatible thin SiN waveguide with an SiO_2 …
