Optical device with a temperature insensitive optical pathlength |
摘要 |
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(Mo<SUB>1-x</SUB>W<SUB>x</SUB>O<SUB>4</SUB>)<SUB>2 </SUB>crystalline material that enables the conditions specified by the FOM to be satisfied. The NaBi(Mo<SUB>1-x</SUB>W<SUB>x</SUB>O<SUB>4</SUB>)<SUB>2 </SUB>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 DeltaT. The NaBi(Mo<SUB>1-x</SUB>W<SUB>x</SUB>O<SUB>4</SUB>)<SUB>2 </SUB>crystalline material exhibits temperature independent transmission characteristics at about room temperature and at a wavelength of about 1550 nm.
