Abstract: A continuous wave (CW) heterodyne light detection and ranging (LIDAR) air velocity sensor system that comprises a first light emitting structure arranged to send a signal light in a first direction in space; a second light emitting structure arranged to produce a local oscillator light having a wavelength different from the wavelength of the signal light by a predetermined wavelength; a receiver arranged to receive light from said first direction in space; and a first optical mixer for mixing the received light with said local oscillator light.

Abstract: A process enables growing thick stoichiometric crystalline and preferably IR- transparent optical PCMO material on Si and other substrates. Sputter deposition is carried out in oxygen-free inert gas (e.g., Ar) environment, which helps to prevent decomposition of the PCMO material over the substrate. In the disclosed process, there is no need to add a seed layer prior to PCMO deposition. Moreover, no post-deposition annealing is needed in a high-temperature and high-pressure oxygen furnace, but an anneal provides certain additional benefits in terms of improved transparency at IR wavelengths. Over a long deposition time for a thick PCMO film on the high temperature (≤450°C) substrates, the PCMO deposition is made repeated cycles of deposition of the PCMO material at the high temperature, each deposition cycle being followed by cooling the PCMO-deposited substrate to a substantially lower temperature (
