Cavity-enhanced spectroscopy in fiber cavities
Optics Letters, 2004We discuss the relative merits of passive and active fiber cavities for ring-down. Ring-down times of approximately 2 micros were recently demonstrated in passive cavities, but operation is restricted to weak evanescent wave interaction. We report on active cavities with amplifiers used for loss compensation, permitting the use of open-path micro-optic

A case is reported of an unusual sinographic appearance and negative microbial cultures, indicating a long-term failure of incorporation of a vascular graft by surrounding connective tissue. Possible pathogenic mechanisms include ruptured lymphatic channels or a low-grade immunologic rejection process.

Cavity optomechanics and cavity optoelectromechanics
71st Device Research Conference, 2013Cavity optomechanics offers unparalleled sensitivity allowing the control of mechanical resonators at quantum level. The dynamic cavity backaction can be utilized to cool a mechanical resonator to its ground state or amplify its motion to limit-cycle oscillations.

Temporal Cavity Solitons in an Active Cavity
OSA Nonlinear Optics 2021, 2021We demonstrate the existence of temporal solitons in a laser pumped below its oscillation threshold. Through bifurcation analysis and experimental measurements, we show how the gain saturation impacts this new localized structure.
