Monolithic beam steering in a mid-infrared, surface-emitting, photonic integrated circuit

Abstract The mid-infrared (2.5 < λ < 25 μm) spectral region is utilized for many purposes, such as chemical/biological sensing, free space communications, and illuminators/countermeasures. Compared to near-infrared optical systems, however, mid-infrared component technology is still rather cru...
