Full-beam asynchronous GaAs laser heterodyne
Abstract
A semiconductor laser optical mixer that generates intensity-modulated light at gigahertz frequencies is described. Two independent or 'asynchronous' GaAs lasers serve as sources. A novel method for wavefront alignment and source optical isolation has allowed 'full-beam' mixing. Heterodyne difference frequencies as large as 10.2 GHz have been generated from both a Si-APD and a GaAs-EAP. The frequency-response characterization of both photodetectors is presented.
