Optical switch with a hot bubble

摘要

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