Abstract :
The investigation deals with computer-aided design of antireflection coatings for photo receiving devices based on InGaAs. These types day and night vision detectors are sensitive and operate in spectral region 0.4 μm - 1.7 μm. Wide-band antireflection multilayer structures from two different materials of high and low refractive index transparent in upper mentioned spectral region are designed and analyzed.
