Tapered light couplers to waveguides
Web2. L-Couplers Basically, light is first fed into a “vertically horn waveguide” and is then funneled into a “throat waveguide”. Both horn and throat waveguides are hollow waveguides with metal shells. The key element is a bent waveguide, which is composed of the throat waveguide and a metal-sandwiching Si 3 N 4 waveguide. WebOct 1, 2010 · The inverted taper coupler, embedded in a polymer waveguide, is optimized for both the transverse-magnetic and transverse-electric modes through tapering the width of the silicon-on-insulator waveguide from 450 nm down to less than 15 nm applying a thermal oxidation process.

WebOther studies of high transmission couplers for PC waveguides [2, 3] have chosen to use linear taper walls, and slant the photonic crystal structure to fol- low the taper walls. We calculate the optical properties of layered systems such as those of Fig. 1 by regarding them as stacked diffraction gratings, having a supercell of D periods (where ... WebJun 23, 2024 · The first system is well known from tapered plasmonic waveguides where adiabatic nano-focusing of light is observed. Its counterpart in the spatiotemporal system is the optical push broom effect where a nonlinear front collects and compresses the signal. Here, we use the slowly varying envelope approximation to describe such systems.
