An 8-Channel Optical Selective Switch for Polarization and Wavelength Multiplexed Fiber Networks

We present an 8-channel chip-based selective switch designed for polarizationand wavelength-multiplexed fiber communication systems. The compact photonic chip, measuring $1.3 \times 0.48 \mathrm{~mm}^{2}$, is fully reconfigurable and can handle randomly polarized light from optical fibers.
