Faculty & Staff Joel FalkProfessor, Department of Electrical and Computer Engineering
EducationPh.D. (Electrical Engineering), Stanford University, 1971 coursesProfessional InterestsDr. Falk's current research efforts are principally concerned with a) the use of semiconductor quantum-well materials for optical switches and modulators and b) diode pumped solid-state lasers. Other recent work has dealt with the use of stimulated Brillouin scattering in phase conjugate devices used for correction of optical phase distortions and in beam combiners as a means of controlling the phase of several high power laser beams so that they can be combined into a single-beam. Other current work investigates the use of fast-Fourier transform technology and optical modulation techniques for the measurement of low-frequency electric fields. Selected PublicationsR. Chu, M.
