Vanadium-compensated 4H and 6H single crystals of optical quality

摘要

An optical device includes a 6H or 4H poly type vanadium compensated silicon carbide (SiC) single crystal of high resistivity configured to transmit light having a wavelength in the range of 420 nm to 4.5 µm. The device can include a window, lens, prism, or waveguide. An optical transmission system includes a light source for generating light having a wavelength in a range of 420 nm to 4.5 µm and an optical device for receiving and transmitting the light, the optical device being a vanadium-compensated SiC single crystal of high resistivity of 6H - or contains 4H polytype
