Abstract

Theoretical studies of backward collinear acousto-optic interactions (BCAOI) in bulk single crystals and single mode glass fibers are described. At very high acoustic frequencies the acoustic wavenumber ka of the guided acoustic waves can be twice of the optical wavenumber ko of the guided optical modes. Thus the incident optical mode propagating in the forward direction is. coupled to that in the backward direction dud to the index grating induced by the guided acoustic mode propagating in the collinear direction if ka = 2 ko. High efficiency is a achieved due to excellent matching between profiles of the electromagnetic fields of incident, diffracted optical beam and the acoustic displacement as well as long interaction length. On- and off- line fiber optic signal processing devices such as frequency shifters, tunable filters, switches and modulators may be built using such BCAOI. Practical considerations for these devices are discussed.
