A New Monolithic Approach for Mid-IR Focal Plane Arrays
Antimonide-based photodetectors have recently been grown on a GaAs substrate by molecular beam epitaxy (MBE) and reported to have comparable performance to the devices grown on more expensive InSb and GaSb substrates. We demonstrated that GaAs, in addition to providing a cost saving substrate for antimonide-based semiconductor growth, can be used as a functional material to fabricate transistor...
متن کاملA Combined Mid-IR/Near-IR Spectrometer
When analysts are faced with the decision of selecting either mid-IR (MIR) or near-IR (NIR) spectroscopy for materials characterization, the decision is usually based on the analytical, sampling, and/ or operational needs. For example, when the greatest analytical specificity is required or certain inorganic materials need to be measured, the choice favors MIR; whereas the need to keep an unsta...
متن کاملMid-IR Silicon Raman Lasers
Silicon is arguably the best Raman medium for the mid-wave infrared spectrum. This new technology can expand the application space of silicon photonics beyond data communication and into biochemical sensing, laser medicine, and LIDAR.
متن کاملNear-ir and Mid-ir Process Analysis — a Critical Comparison
Over the past several years, both near infrared (NIR) and mid infrared (MIR) spectroscopy have steadily gained acceptance as powerful methods for at-line and on-line analysis. These methods share the advantages of high speed, robust calibration, and low service requirements compared to more established process analytical techniques such as gas chromatography. However, despite their many similar...
متن کاملOne-Watt level mid-IR output, singly resonant, continuous-wave optical parametric oscillator pumped by a monolithic diode laser.
We report more than 1.1 Watt of idler power at 3373 nm in a singly resonant optical parametric oscillator (SRO), directly pumped by a single-frequency monolithic tapered diode laser. The SRO is based on a periodically poled MgO:LiNbO3 crystal in a four mirror cavity and is excited by 8.05 W of 1062 nm radiation. The SRO pump power at threshold is 4 W. The internal slope-efficiency and conversio...
