WebIn the consequent analysis of this L3 cavity, it was found that the Qcan be further increased by a slight change of the overall hole radius. This brought the maximum FDTD-computed Qof the design, obtained for R= 0:255ainstead of 0:25a, to 20:9 106 (GME-computed Q: 20:0 106). The resonance frequency of this cavity mode is !=(2ˇ) = 0:254a=c, which, WebFIGURE 2: (a) High power μ-PL spectrum of a L3 cavity with 0.2a inner hole shift taken at 10 K. The inset shows a high resolution μ-PL spectrum with Q-factors exceeding 8200 emitting at 1.55 μm. (b) M1 Q-factors as a function of excitation laser power.

WebJan 28, 2024 · High-Q cavities are great for many applications: think of lasers with really sharply defined wavelengths, very sensitive sensors, or high-precision filters. The simple cylinder described in this paper isn't ready for any of these applications yet, but it is headed in that direction. Of course, this is only a light summary of the paper. WebApr 1, 2013 · A photonic microcavity with ahigh Q factor of 1.8741 × 107 and a modal volume V of 0.351 is demonstrated.
