A 1 × 8 Optical Switch of Mach-Zehnder Interferometers Using Si-Waveguides with Ferroelectric Liquid Crystal Cladding

摘要

We fabricated a 1×8 optical switch using tunable phase shifters in Si-waveguides with ferroelectric liquid crystal cladding. The tunable phase shifters were 340 μm long. A switching operation was demonstrated at a 1550-nm wavelength.
