Wavelength add-drop switching using tilting micromirrors
TL;DR: In this paper, a single-mode optical fiber switch which routes individual signals into and out of a wavelength multiplexed data stream without interrupting the remaining channels is described, and the total fiber-to-fiber insertion loss for the packaged switch is 5 dB for passed signals and 8 dB for added and dropped signals, with 0.2 dB polarization dependence.
