An acousto-optical waveguide device with tunable and unpolarized response characteristics and an acousto-optical waveguide device, tunable, with a polarization inde pendent response, and a method for the acousto-optical processing optical signals)

摘要

The present invention relates to a polarization mode transducer of two separate polarizing elements of an optical signal, first and second polarization selective elements respectively located below and above the polarization mode transducer, and at least one optical waveguide comprising two polarizers Optical waveguide device comprising a substrate made of a birefringent photoelastic material having at least one compensating end for polarization mode conversion for transmitting the elements in a combined form, Optical switching of an optical signal based on two steps of converting polarization elements of an optical signal transmitted in a state in which each of the optical signals is separated or not separated by acousto-optic interaction with two acoustic waves.
