Optical resonators with quality factor as high as 875 million are demonstrated. These silicon-chip-based devices are fabricated using only lithography and chemical etching, thereby expanding integration opportunities and possible applications.
We report the detection of 11.5-nm radius polystyrene beads in an aqueous environment at a signal-to-noise-ratio of 18:1 by monitoring the split frequency steps of a 5.7-KHz-linewidth microlaser. The thermal-optical effect is also observed.
Optical resonators with quality factor as high as 750 million are demonstrated. These silicon-chip-based devices are fabricated without silica reflow, thereby expanding the range of integration opportunities and possible applications.
We present design and simulation results of a novel nanomechanical sensor using a silicon cantilever comprising two-dimensional (2-D) photonic crystal (PC) microcavity resonator structure. A U-shaped silicon line defect in a 2-D photonic crystal is considered as a waveguide for confining light propagation within waveguide, while two-hole pairs are placed along this silicon waveguide as a optical reflector...
