Abstract

Since the advent of slot optical waveguides by Lipson, normally SOI based slot optical waveguides have been under consideration. It has been found that glass based slot optical waveguide structures, where refractive index contrast ratio is comparatively less can also play important role in forming complex nano size optical devices. We have made use of power confined inside low index slot region for a double slot structure, where central high index slab is acting as a cantilever. Novel optomechanical sensor has been proposed based on variation in power confined inside low index slot region due to the movement of central high index slab under the action of external force (temperature, pressure, humidity, etc.).
