The acoustic wave, in turn, can scatter and modulate light. The interplay of the two wave phenomena has drawn the attention of researchers since the 1880's. Our group is studying light-and-sound interactions in standard optical fibers and in silicon-photonic integrated circuits. In this seminar, I will present some of our latest, yet unpublished results of the last year: Inter-polarization scattering in standard and polarization-maintaining fibers, optical stimulation of acoustic vortex beams, and integrated microwave-photonic filters with arbitrary transfer functions and few-MHz linewidths.    Very short bio: Prof. Avi Zadok joined the Faculty of Engineering, Bar-Ilan University in 2009. His research interests include fiber optics, nonlinear optics, opto-mechanics, and photonic integrated circuits.
