 Low Drive Power Compact AOTF For Infrared Wavelengths

Abstract:

The novel technique described in this proposal has the potential
to dramatically reduce the drive power required by a resonant
acousto-optic tunable filter (AOTF) device in the infrared
wavelengths. A compact and on-is [110] acoustic wave propagation
resonator using tellurium dioxide and/or the crystal family such
as mercurous chloride and Ti-As-Se is proposed. This new approach
has three advantages: highest figure of merit; highest resonant
Q; and compact size resonator. This on-axis resonator will have
gain of 7.5 times over off-axis resonant devices. In contrast to
the current commercial off-axis AOTF, high drive power and large
size are required for use at infrared wavelengths. Applications
in two- dimensional spectral images have the need to develop this
new low drive power and compact AOTF for use at 2 to 5 microns
wavelength. This new technique can be extended to longer infrared
wavelengths.

Commercial applications include spectral imaging, medical
diagnostics, chemical process control, thermal emission
diagnostics, toxic gas and liquid monitors, blood gas
diagnostics, biochemistry, aerospace, planetary, and earth
studies.
