Alejandro Grine is a 4th year PhD graduate student in professor Ming Wu's group. He recieved his S.M. from MIT and his B.S. from the University of New Mexico both in Electrical Engineering. He has performed research on avalanche photodiodes, microcavity lasers, and optomechanical oscillators.
He worked for Sandia National Laboratories from 2002-2012 where he was most recently a Process Integration Engineer in the Heterojunction Bipolar Transistor program.
He expects to graduate in 2014.
Low Power, Low Noise Cavity Optomechanical Oscillators [BPN651]
Cavity optomechanics is a new and rapidly advancing field in which light is used to alter the properties of a mechanical element. Our project specifically aims to enhance mechanical motion by means of optical radiation pressure in a cavity of both high optical and mechanical quality factors. When enough light is built up in such a cavity, the mechanical self-oscillation results in precisely modulated light at the cavity output. Though there may be numerous applications for cavity optomechanics, we seek to use optomechanical oscillators as a replacement for power-hungry microwave oscillators in chip scale atomic clocks. This work focuses on the RF photonic experimentation necessary to characterize and improve microfabricated optomechanical devices for the target application which requires a low phase noise optical carrier oscillator capable of operating at 3GHz.
