1 x 2 wavelength-selective switch for three-channel wavelength-division multiplexing systems.
A 1 x 2 wavelength-selective optical switch for three-channel wavelength-division multiplexing systems is proposed and tested. The switch is constructed by a cascade connecting three switch elements, each of which controls the polarization state of a certain wavelength of light. A 1 x 2 switch for a three-channel multimode fiber system (channel wavelengths 1.2, 1.25, and 1.3 microm) is fabricated. Its measured insertion losses and cross-talk attenuations are <0.9 and >14.7 dB, respectively, for all switching modes and all channels.
