Operational temperature increase of CW THz QCLs to 77 K has enabled us to employ solid nitrogen (SN2) as the cryogen. A roughing pump was used to solidify liquid nitrogen and when the residual vapor pressure in the nitrogen reservoir reached the pump

We report on a new two-photon cryomicroscope which consist of a compact laser-scanning microscope combined with a motorized heating and freezing stage. Samples can be cooled down to -196 °C (77 K) and heated up to 600 °C (873 K) with adjustable hea

In this paper, we have investigated cryogenic temperature response of long-period fiber gratings (LPFGs) inscribed on standard photosensitive single-mode fibers without any polymeric coatings. The resonance wavelength of the fabricated LPFG, which wa

Lithium niobate (LN) modulators have been for years the devices of choice for the telecommunication market due to their high modulation rate and their robustness. Matching RF and optical velocities has been the most critical factor that limited this

The tellurite-tungstate glasses containing small amounts of rare-earth ions have been studied experimentally at 77 and 293 K using spectroscopic methods. The photoluminescence (PL) studies reveal the emission of efficient green-yellow light from Tb3+

We present the characterization of a boron doped hydrogenated amorphous silicon (a-Si:H) thermosensor bolometer array for far infrared detection. The array was fabricated over a silicon wafer on a 0.4 μm silicon-nitride (Si 3 N 4 ) layer. Wet bulk m

State of the art high performance cooled IR systems need to have more than just excellent E/O performance. Minimum size weight and power (SWaP) are the design goals to meet our forces' mission requirements. Key enabler for minimum SWaP of IR imagers
