Optical switch with a hot bubble

Based on microfluidics and optical communication technology, an optofluidic switch is proposed, where the hot bubble driving technology is used. And switch-on or switch-off and the optical path switching are realized by a hot bubble in the microchannel. The growth and condensation of the gas bubble in the microchannel is controlled by temperature. The optical switch has the advantages of small volume, simple and compact structure, low driving voltage, low power consumption, no mechanical moving parts and easy operation. This paper introduces the structure, processing technology and working principle of this optical switch.
