Linear waveguide taper
Nettet15. feb. 2024 · A large, ultrahigh-Q factor, and single-mode operation silicon ring resonator was designed based on a strip silicon photonics waveguide, comprising MMWG, 90° Bezier bends, linear taper, and SMWG coupler. The fabricated the microring resonator showed an ultrahigh-Q factor of 1.54 × 10 6 and an FSR of 0.036 nm. The … NettetA waveguide in circuit theory is described by a transmission line having a length and characteristic impedance. In other words, the impedance indicates the ratio of voltage to current of the circuit component (in this …

NettetThe compact taper is highly tolerant to fabrication variations; ±100 nm change in the taper and end waveguide width varies the taper transmission by <5%. The footprint of the device, i.e., the taper along with linear gratings, is ≈442 μm2, 11.5× smaller than the adiabatic taper. The taper with linear gratings provides coupling efficiency ... NettetThe plot is shown in the accompanying figure. The reflectance values computed using the two methods of mode decomposition and flux are nearly identical. For reference, a line with quadratic scaling is shown in black. The reflectance of the linear waveguide taper decreases quadratically with the taper length consistent with analytic theory.
