Abstract
This disclosure describes a system and method for providing multi-material selection for elimination of back-reflected acoustic waves to produce acoustic compensation of an electro-optic modulator (EOM) for use in the Long-Wave Infrared (LWIR) and Mid-Wave Infrared (MWIR) spectrum.
Claims20
A system, comprising:
- a non-centrosymmetric crystal;
- a load material;
- and
- a matching layer operable to reduce a generation of back-reflected acoustic waves, wherein:
- an acoustic impedance of the matching layer is determined according to a square root of a product of an impedance of the non-centrosymmetric crystal and an impedance of the load material.

A method, comprising:
- placing a matching layer between a non-centrosymmetric crystal and a load material, an impedance of the non-centrosymmetric crystal is different than an impedance of the load material;
- determining a thickness of the matching layer as an integer multiple of a quarter wavelength of an acoustic wave;
- and
- reducing a generation of back-reflected acoustic waves via the matching layer.
