Abstract
We obtained the wavelength selective operation in a grating Si rib waveguide that
has an ferroelectric liquid crystal (FLC) cladding. The FLC cladding gives a phase shift
change for the traveling lightwave in the waveguide in accordance with the polarity of
the applied voltage. We propose the wavelength selective filter using this operation and
demonstrate the selective switching and the tunable operation of our fabricated device.
We also report its time response and dependence on the applied voltage and propose a new
operating method to achieve a continuous phase change by using the FLC layer that has
binary characteristics.
