Continuous operation of a hybrid solid-liquid state reconfigurable photonic system without resupply of liquids

Abstract

Optofluidics offers a number of potentially transformative advantages for photonic systems. At present however there are a number of technological roadblocks that prevent the practical integration of liquid-state elements into traditional high-speed solid-state photonic systems. Two of the most important of these are the need for continuous resupply of liquids and the difficulty in shuttling light between the liquid- and solid-states. In this paper we present an integrated system that solves both these problems. For the first time we demonstrate direct evanescent and end-fire coupling between liquid- and solid-state waveguides and an on-chip fluid core/cladding separation and recirculation system that reduces the consumption of liquids more than 200 fold over the state of the art. The device is operated continuously for over 20 h without performance degradation or requiring the replenishment of liquids. We believe that our system represents an important step towards the development of practical optofluidically enabled photonic systems.
