Coupling of high-quality-factor optical resonators
We improve theoretically and experimentally the problem of the coupling between a high Q-factor resonator and its external coupler. We have observed oscillations of ringing induced by the sweeping of the excitation frequency of an active micro sphere. Thanks to this approach, quality factor of an optical resonator was measured and we obtained Q = 5.8×10.
متن کاملIntegrated high-quality factor optical resonators in diamond.
The realization of an integrated diamond photonic platform, based on a thin single crystal diamond film on top of a silicon dioxide/silicon substrate, is reported. Using this approach, we demonstrate high-quality factor single crystal diamond race-track resonators, operating at near-infrared wavelengths (1550 nm). The devices are integrated with low-loss diamond waveguides terminated with polym...
متن کاملUltra-high quality factor optical resonators based on semiconductor nanowires.
We propose a platform to achieve ultra-high Quality factor (Q) optical resonators based on semiconductor nanowires. By defining onedimensional photonic crystal at nanowire ends and engineering the microcavity pattern, cavities with Q of 3 x 10(5) and mode volume smaller than 0.2(lambda/n)(3) have been designed. This represents an increase of almost three orders of magnitude over the Quality fac...
متن کاملQuality Factor Enhancement of Optical Channel Drop Filters Based on Photonic Crystal Ring Resonators
In this paper, a channel drop ring resonator filter based on two dimensional photonic crystal is proposed which is suitable for all optical communication systems. The multilayer of silicon rods in the center of resonant ring enables one to adjust resonant wavelength of the ring and enhance power coupling efficiency between ring and waveguide. Refractive index and radius of multilayer rods insid...
