Abstract
The thermo-optic behavior of an optical path over a range of temperatures is controlled by determining a figure of merit (FoM) for the optical path and including in the path a body of NaBi(MoWO)crystalline material that enables the conditions specified by the FOM to be satisfied. The NaBi(MoWO)crystalline material is highly transparent at a wavelength of radiation propagating in the path, and has a coefficient of thermal expansion (CTE) and a refractive index n such that the CTE and dn/dT of the etalon compensate one another so as to perform frequency discrimination that is essentially temperature insensitive over the range ΔT. The NaBi(MoWO)crystalline material exhibits temperature independent transmission characteristics at about room temperature and at a wavelength of about 1550 nm.
