Abstract

By exploiting the Kerr effect and the gradient of the composition ratio m, Nb/(Ta + Nb) in mol%, in KTa_1-xNb_xO₃ (KTN) crystals, we have designed an electric-field-controlled optical switch. The operating principle of the switch is described. During the switching process, the incident linearly polarized beam is orthogonally deflected as it propagates through the crystals. The g₁₁/g₁₂ ratio (>10), wavelength range (491-1064 nm), I-V characteristics (0-800 V), extinction ratio (0-1), gradient of Curie temperature (21-22.9 °C), response time that may be in ns order, and influence of the photorefractive effect were studied. The results show that our design provides a new kind of optical switch with macro scale (mm order), adjustable extinction ratio (0-1), wide wavelength range (491-1064 nm).
