Ultra broadband mid-IR detectors using multilayer anti-reflection coupling
- View All
Ultra broadband mid-IR detector is demonstrated in the spectral region at 2-4 um. The light coupler is composed of multilayer dielectric layers. A 60 % enhancement of transmittance is achieved at light incident angles θ=0°-75°. © 2011 OSA.
