Nanosecond response of bulk-optical Bragg-diffraction modulator based on periodically poled LiNbO3
Nanosecond response of bulk-optical Bragg-diffraction modulator based on periodically poled LiNbO3
For the first time transients are measured for a bulk-optical Bragg-diffraction modulator based on an electro-optically induced grating in periodically poled LiNbO3 (PPLN). Optical pulse risetimes of 1.2 nsec are reported with a first order diffraction efficiency of 76 % for circular Gaussian beams. The fast risetime is accounted for by a substantially suppressed excitation of acoustic thickness modes and careful electrode design. The device could replace acousto-optical Bragg-deflectors for many applications due to a reduction of the risetime by more than an order of magnitude.

Abstract
For the first time transients are measured for a bulk-optical Bragg-diffraction modulator based on an electro-optically induced grating in periodically poled LiNbO3 (PPLN). Optical pulse risetimes of 1.2 nsec are reported with a first order diffraction efficiency of 76 % for circular Gaussian beams. The fast risetime is accounted for by a substantially suppressed excitation of acoustic thickness modes and careful electrode design. The device could replace acousto-optical Bragg-deflectors for many applications due to a reduction of the risetime by more than an order of magnitude.
