Webcoupling scheme is for example effectively implemented in III-V-to-Si-photonics hybrid laser integration. Here, the goal is to transfer light between the Si-waveguide and the III-V wave-guide. Efficient optical coupling was shown for double-taper structures of the silicon waveguide ends [10], [11]. Adiabatic optical coupling was recently also ... WebCurrently, a linear taper connected a 12-μm-wide grating coupler and a 0.5-μm-wide single-mode silicon waveguide must be longer than 400 μm to achieve low-loss propagation. …
WebOptiBPM is a computer-aided design software tool enabling design of complex optical waveguides, which perform guiding, coupling, switching, splitting, multiplexing, and demultiplexing of optical signals in photonic devices. OptiBPM is based on the Beam Propagation Method (BPM) of simulating the passage of light through any waveguide …
WebFurther measurement of the waveguide-to-waveguide coupling devices in the glass showed that the total insertion loss of two symmetric SSC structures through two ~50 μm-diameter coupling ports was ~6.73 dB at 1310 nm, which was only about half that of non-SSC structures with diameters of ~9 μm at the same coupling distance. canine gait analysisWebCorrugated horn antenna with a bandwidth of 3.7 to 6 GHz designed to attach to SMA waveguide feedline.
