Measurement and Control of Transverse Photonic Degrees of Freedom via Parity Sorting and Spin-Orbit Interaction

Date: 
May 10, 2010 (All day)
Speaker: 
Cody Leary

We discuss new methods for the measurement and control of transverse photonic degrees of freedom. We demonstrate an interferometric mode sorter for two-dimensional (2-D) parity of transverse spatial states of light, present the first experimental 2-D parity sorting measurements of Hermite-Gauss transverse spatial modes, and discuss applications to quantum information processing.

A Fully Tunable Microcavity

Speaker: 
Dr. Russell Barbour

Semiconductor optical microcavities that combine high Q-factors with a small mode volume play a vital role in modifying the interaction between light and matter. Several interesting phenomenon arise when an emitter is introduced into such a cavity. These include enhancement or suppression of the spontaneous emission rate (weak coupling) and normal mode splitting (strong coupling).

Towards Atomic-Scale Optical Probes

Speaker: 
Dr. Jeffrey Guest

Over the past two decades, ultra-high vacuum (UHV) scanning tunneling microscopy (STM) and single particle laser spectroscopy have made great strides in measuring and controlling nanoscale and atomic-scale systems incomplementary ways.

Optofluidic ring resonator technology platform for rapid and sensitive biological and chemical sensing

Date: 
February 10, 2009 (All day)
Speaker: 
Dr. Xudong Fan

The optical ring resonator is an emerging sensing technology that has recently been under intensive investigation. In a ring resonator, light propagates in the form of whispering gallery modes (WGMs), which results in a light-analyte interaction length much longer than the resonator physical size. Consequently, the ring resonator can achieve a much improved detection limit, lower sample volume, and larger integration density than the traditional waveguide or optical fiber based sensor.
