摘要：
Waveguides were fabricated by deposition of boron nitride thin films onto glass substrates by a microwave plasma enhanced chemical vapor deposition (PECVD) process. We have characterized the optical linear properties of the as-deposited layers by m-lines spectroscopy. We have used a simple method based on the shift of the synchronous angles of the guided modes to investigate the electro-optic tensor r(ij) using co-planar electrodes. With TM polarized light the value of r(eff) computed is of the order of 5 pm V-1. (C) 1999 Elsevier Science S.A. All rights reserved.
