Professional Interests

Dr. 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.
