Abstract

The detailed behavior of circular bend attenuation in GaAs/AlGaAs rib waveguides is explored both experimentally and theoretically. Our results show a strong polarization dependence of the bend loss and coherent coupling oscillations much weaker than predicted by beam-propagation calculations.

Figures (2)

Fig. 1
Fig. 1

Schematic of the experimental geometry. W, rib width; h, rib height; ΔR, radius spacing. For clarity, fewer bends are shown than were actually present on a chip. Arrows on the left indicate optical polarization designations.

Fig. 2
Fig. 2

Bend-induced attenuation of 90° circular bends as a function of radius and polarization. Only excess bend loss is shown; propagation losses associated with transmission through straight guides of the same total length as the bent structures are not included. Experimental data are represented by error bars (TE polarization) and asterisks (TM polarization). Solid curves are the result of beam-propagation-method calculations, with loss values computed for 0.1-mm steps in radius.
