Optical strip waveguides in KNbO3formed by He ion implantation

摘要

Permanent optical strip waveguides in single crystals of KNbO3were produced with MeV He ion implantation. Guided TE00modes were observed and the propagation losses were characterized at the wavelengths of 514, 632, and 860 nm. Waveguide propagation losses of 1.4 dB/cm were measured at 632 nm.
