Infrared radiator

Pulsed high-intensity infrared radiators can be used for gas analysis, spectroscopy, and calibration. The PulsIR radiators offer high emissivity at either 2-5 or 8-12 µm, using a 6x tungsten filament bulb. Radiator life is rated at more than three years when operated at 1 Hz, with a 10% duty cycle. Electrical pulsing eliminates the need for a chopper.

IceCube ice anisotropy could be due to birefringent polycrystals

A twofold difference in ice attenuation in perpendicular directions in the IceCube experiment could be explained by a birefringent structure of the microcrystals in the ice.

A photonic crystal (PhC) with a heterostructure cavity achieves double resonance even though it has only one bandgap, not two; the second resonance is provided by a “bound state in the continuum” (BIC). The heterostructure cavity includes a core, a transition region, and an outer region (delineated here by dotted lines). The relevant resonant mode is confined to the core region. Creating such a PhC out of a nonlinear optical material allows PhC-based optical frequency doubling for the first time.

Nonlinear Optics: Light-trapping, frequency-doubling photonic crystal is first of its kind

The photonic crystal traps the fundamental frequency via a conventional bandgap and the doubled frequency using a “bound state in the continuum.”
