High Frequency Wideband I.O. Bragg Cell

Abstract

Reported are the results of a program to improve the high frequency acousto-optic diffraction efficiency of surface wave Bragg cells to extend the range of integrated optical spectrum analyzers. The acousto-optic performance of waveguides formed by the recently developed technique of proton exchanging lithium niobate (PE:LiNbO3) was determined at frequencies in the 1 GHz region. Diffraction efficiencies of single transducer PE:LiNbO3 Bragg cells were measured at 794, 893, 1021, and 1340 MHz and compared to titanium indiffused lithium niobate (Ti:LiNbO3) results. Piezoelectric and elastic properties, along with optical loss and scatter characteristics, were determined for both annealed and unannealed PE:LiNbO3 and titanium indiffused proton exchanged (TiPE:) LiNbO3 waveguides.
