Beam Combination Boosts Power for Quantum Cascade Lasers
Quantum cascade laser (QCL) sources offer a compelling option in the MIR range, but they currently deliver limited output power. This drawback is driving growing interest in methods that would allow QCLs to combine their beams passively and in a compact format to permit higher power outputs and to help integrate these sources in new applications.

Optical Surface Analysis: Focusing on the Fundamentals
Today’s instruments for measuring optical components deliver increasingly higher resolution, larger measurement areas, and greater analysis functions. In addition to improving results, the added sensitivity and analysis options can also increase measurement variability, which can inadvertently raise the number of good components that must be reworked or scrapped.

HyperFine Brillouin Spectrometer

LightMachinery Inc.
The great challenge with Brillouin spectroscopy is that the scattered signal from the un-shifted wavelength of the laser can overwhelm the small Brillouin shifted return signal. LightMachinery has combined its leading-edge HyperFine spectrometer with a very narrow band tunable filter to suppress the bright un-shifted laser frequency.

Dual-Band IR Detector Can Be Integrated with Camera Chips
Scientists at the Forschungszentrum Jülich (Jülich Research Center) and the Politecnico di Milano (Polytechnic University of Milan) have developed an infrared (IR) detector that provides a bias-switchable spectral response in two distinct IR bands. When the bias voltage for the detector is reversed, the device switches from the near-infrared (NIR) to the shortwave infrared (SWIR) band. The dual-band photodetector, which is silicon (Si)-based, can be integrated into existing camera chips and smartphones.
