2-DIMENSIONAL ANALYSIS OF A DIELECTRIC WAVE-GUIDE MIRROR

We present the two-dimensional (2-D) mode numerical analysis of a diel ectric waveguide mirror with arbitrary structure angle, This work is a n extension of a previously reported one-dimensional (1-D) mode analys is which accounts for the transverse variation, in addition to the lat eral, of the waveguide modes, Inclusion of the transverse confinement is very important and has a significant effect on the predicted charac teristics of the dielectric mirror, The dependence of the modal reflec tion on mode confinement and transverse and lateral mirror tilt is eva luated, Ln addition, the farfield is predicted and results in an unusu al and unique crescent shaped distribution for angled incidence to the mirror, These mirrors are finding increasing use in many optical devi ces and systems including turning mirrors, lasers, and optical switche s and couplers, With this expanding application, the characterization of these mirrors is paramount.
