Optical Spectroscopy of Microcavities
1997Microcavities, such as microspheres, possess morphology-dependent resonances (MDR’s). In this chapter light coupling mechanisms to MDR’s is examined. The novel mechanism of excitation of the microsphere with an optical fiber coupler (OFC) provides spatially and spectrally selective, as well as enhanced light coupling to the MDR’s, when compared with ...

AbstractBoth rich fundamental physics of microcavities and their intriguing potential applications are addressed in this book, oriented to undergraduate and postgraduate students as well as to physicists and engineers. We describe the essential steps of development of the physics of microcavities in their chronological order.

2007 Conference on Lasers and Electro-Optics (CLEO), 2007
A novel all-fiber spliced microcavity for chemical and biological optical studies is described. Its design allows coupling with low loss light from a fiber into a liquid or gas contained in a capillary or PCF.

Quantum Optoelectronics, 1993
Microcavity lasers potentially will have ultra-low thresholds in the micro ampere range or even lower. The vertical-cavity surface-emitting laser (VCSEL) structure represents the most straightforwardly produceable device which can scale down to ultra-small cavity dimensions and active material volumes.

Recycling microcavity optical biosensors
Optics Letters, 2011Optical biosensors have tremendous potential for commercial applications in medical diagnostics, environmental monitoring, and food safety evaluation. In these applications, sensor reuse is desirable to reduce costs. To achieve this, harsh, wet chemistry treatments are required to remove surface chemistry from the sensor, typically resulting in reduced

Photophysics of J‐aggregate microcavities
physica status solidi (b), 2008AbstractWe have developed a model in order to account for the photo‐excitation dynamics of J‐aggregate films and strongly coupled J‐aggregate microcavities. The J‐aggregates are described as a disordered Frenkel exciton system in which relaxation occurs due to the presence of a thermal bath of molecular vibrations. The link between the J‐aggregate film

Bistability in buckled dome microcavities
Optics Letters, 2015We describe optical bistability in monolithically integrated, curved-mirror Fabry-Perot microcavities. The cavities were fabricated by controlled formation of circular delamination buckles within sputtered Si/SiO(2) multilayers. The dominant source of the bistability is heating due to residual absorption in the mirror layers, which leads to out-of ...

Fermi resonance in optical microcavities
Physical Review E, 2015Fermi resonance is a phenomenon of quantum mechanical superposition, which most often occurs between normal and overtone modes in molecular systems that are nearly coincident in energy. We find that scarred resonances in deformed dielectric microcavities are the very phenomenon of Fermi resonance, that is, a pair of quasinormal modes interact with each

AbstractIn this chapter we provide an overview of microcavities. We present the variety of semiconductor, metallic and dielectric structures used to make microcavities of different dimensions and briefly present a few characteristic optical effects observed in microcavities.
