Abstract :
This paper presents a micro-fluidic-optical switch via side coupling multi-droplet resonators to an optical waveguide. The optical switch consists of a Polydimethylsiloxane (PDMS) waveguide, a T-junction for oil droplets generation and two optical fibers for light detection. The states of the optical switch are determined by the resonant modes and the distribution of the droplets. Compared to the solid optical resonator switch, the micro-fluidic-optical switch has various advantages, such as wide wavelength tuning range, easy fabrication process, simple manipulation, and low cost. The diameters of the droplets generated are within the range of 20 mum to 50 mum.
