Focal Plane Array Based on Silicon Nitride for Optical Beam Steering at 2 Microns

Focal Plane Array Based on Silicon Nitride for Optical Beam Steering at 2 Microns

The 2 μm wavelength is ideal for light detection and ranging and gas sensing due to its eye-safe operation, strong molecular absorption targeting, and low atmospheric scattering—critical for environmental monitoring and free-space communications. The existing 2 μm systems rely on mechanical beam ste...
