We present a theoretical analysis and experimental measurements of broadband optical wavelength conversion by four-wave mixing in semiconductor traveling-wave amplifiers. In the theoretical analysis,… (More)
Microcavities can enter a regime where radiation pressure causes oscillation of mechanical cavity eigenmodes. We present a detailed experimental and theoretical understanding of this effect, and… (More)
Two device geometries that enable structural coexistence are micro-mechanical and optical resonators. In one geometry, a micro-cantilever mechanical resonator also functions as a mirror in a… (More)
Stability and continuous operation are important for almost any use of a microcavity, we demonstrate here experimentally and theoretically self-stable equilibrium solution for a pump-microcavity… (More)
Radiation pressure can couple the mechanical modes of an optical cavity structure to its optical modes, leading to parametric oscillation instability. This regime is characterized by regenerative… (More)
Using ion beam implantation of erbium a silica micro-disk laser on silicon chip is demonstrated. A clear transition of spontaneous emission to stimulated emission is observed, with threshold powers… (More)
We demonstrate for the first time, self generation of mechanical vibrations at RF frequencies stimulated directly by the radiation pressure of circulating photons within optical micro-cavities.
The efficiency of broadband optical wavelength conversion by four-wave mixing in semiconductor traveling-wave amplifiers is measured for wavelength shifts up to 65 nm using a tandem amplifier… (More)
We investigate the role of absorption and scattering losses in limiting the quality factor of toroidal micro-cavities by monitoring the threshold power for thermal bistability in these structures.
