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

Two‐dimensional microcavity lasers
Laser & Photonics Reviews, 2011AbstractAdvances in processing technology, such as quantum‐well structures and dry‐etching techniques, have made it possible to create new types of two‐dimensional (2D) microcavity lasers which have 2D emission patterns of output laser light although conventional one‐dimensional (1D) edge‐emitting‐type lasers have 1D emission.

Titanium enhanced Raman microcavity laser
SPIE Proceedings, 2014Whispering gallery mode microcavities are ideally suited to form microlaser devices because the high circulating intensity within the cavity results in ultralow lasing thresholds. However, to achieve low-threshold Raman lasing in silica devices, it is necessary to have quality factors above 100 million. One approach to circumvent this restriction is to

CLEO 2024
We demonstrate, for the first time, an optical microresonator with plasma inside. This plasma cavity might impact new types of plasma-based optical interconnects and electrically pumped ultracoherent-microlasers.

Applied Physics Letters, 1995
We introduce and analyze a new type of high-Q microcavity consisting of a channel waveguide and a one-dimensional photonic crystal. A band gap for the guided modes is opened and a sharp resonant state is created by adding a single defect in the periodic system.

Resonant microcavity photodetectors
SPIE Proceedings, 1993Photodetectors with both high bandwidth and high quantum efficiencies are crucial components for a variety of key technologies such as telecommunications, information processing, storage and sensing. The most widely used devices today are p.. i-n photodetectors and avalanche photodetectors.

Rotating optical microcavities
2007 Conference on Lasers and Electro-Optics - Pacific Rim, 2007The Sagnac effect in rotating microcavities is studied theoretically and numerically. The frequency shift due to the Sagnac effect occurs as a threshold-like phenomenon for the angular velocity in a rotating microcavity. Above the threshold, the eigenfunctions of a rotating microcavity become rotating waves while they are standing waves below the ...

Microcavity Semiconductor Lasers
1998We review the theory and recent experimental developments in microcavity semiconductor lasers and their implications. Particular attention is paid to microdisk lasers which support whispering gallery modes. InGaAsP/InP microdisks have recently been fabricated in our laboratories and have been pumped optically, resulting in the first achievement of CW ...
