An ultralow-loss silicon planar waveguide crossing operating in the O-band was
experimentally demonstrated based on the Gaussian beam synthesis method. Elliptical …

Waveguide crossing is an important integrated photonic component that will be routinely
used for high-density and large-scale photonic integrated circuits, such as optical switches …

We fabricated optical directional couplers with Si-wire waveguides and demonstrated their
fundamental characteristics. Their coupling-length was extremely short, several …

In this thesis, guiding and routing of optical signals in high index difference ([delta] m)
waveguide systems are studied for silicon microphotonic applications. High [delta] n …

This thesis describes the design, simulation, fabrication and characterisation of
microphotonic silicon waveguide components on silicon-on-insulator (SOI) substrates. The …

Silicon slot waveguide intersections are necessary for photonic-integrated circuits based on
silicon slot waveguides. We theoretically investigate a compact silicon slot waveguide …

Current paper introduces efficient silicon wire waveguide crossing by means of vertical
coupling of tapered Si wire with upper SU-8 polymer wide strip waveguide through a silica …

Conventional silicon optical waveguides can have efficient coupling to optical fibers using
grating couplers, but there is no structure of comparable coupling efficiency, optical …

We investigate the loss mechanism in three-moded multimode-interference couplers that are
the building blocks of a compact and low-loss waveguide crossing structure. Broadband …
