Abstract
Optical feedback is the major cause in the deterioration of laser signal quality. To suppress reflections from connectors, tilting the endface of the waveguide is beneficial [1][2]. Tilting the endface prevents the coupling of the reflected beam back into the fundamental mode. Considerable effort has also been made in obtaining an antireflective coating for the endfaces of dielectric waveguides [3]-[5]. However, the full-wave analysis of thèse reflection problems has not appeared to date. The purpose of this paper is to analyze the reflection problems of optical waveguides using the finite-difference time-domain (FDTD) method [6][7] combined with the absorbing boundary condition [8], The FDTD method allows us to obtain information on reflected power for both TE and TM polarizations.
