The effect of mirror curvature was studied for its influences on the operation of the wavelength-selective switches. Expressions for the curvature-induced losses and path length differences were developed. It was found that curvature gives rise to a fixed dispersion, which matches the experimental observations. Furthermore, it was shown that mirror curvature is responsible for passband tilt in the attenuated state with SDD tilt mirrors.
