Abstract
We report an on-chip integrated ferroelectric liquid crystal (FLC) waveguide
structure suitable for telecommunication applications. Single gaps with different widths
of 5, 10, and 20 μm inside individual silica waveguides were filled with an FLC
mixture. The waveguide devices operate as a binary switch or an attenuator in a
temperature range from 30 °C to 60 °C. The FLC mixture exhibited a good
alignment quality in these gaps without alignment layers. A good extinction ratio of up
to 33.9 dB and a low insertion loss of <4.3 dB at λ = 1550 nm were
observed. Switching times of <100 μs were obtained for the low electric fields
applied in this experiment.
