This paper introduces a novel array optical switch based on piezoelectric ceramics and the micro-fluidic control technology

with a focus on the optical power loss of its waveguide layer.It analyzes and simulates the coupling loss of the waveguide layer using Opti-FIBER and experimentally measures the coupling losses in different conditions.The results show that this switch has such advantages as simple structure

fast response

100 μs

and low loss

minimum theoretic insertion loss 0.042 524 dB.
