Photodetectors and birefringence in ZnP2–С2h5 crystals

Abstract

The spectral dependences of refractive indexes no(n⊥), ne(n||) and Δn=no(n⊥)−ne(n||) were studied in ZnP2–C2h5 crystals. The intersection of no(n⊥) and ne(n||) was found for λ0=0.906μm. The crystal possesses positive dispersion Δn=no(n⊥)−ne(n||) in the region where λ>λ0, and a negative dispersion is observed in the region where λ<λ0. The electrical, spectral and azimuth characteristics of monolith n–р- and Ме-n–р-ZnP2C2h5 and discrete ZnP2–C2h5–ZnP2–D48 structures were studied, and a prognosis was made on the usage perspective of these devices.
