Issue Date: | 2013 | Citation: | Ho, W.F., Chan, H.P., Yang, K.L. (2013). Planar optical waveguide platform for gas sensing using liquid crystal. IEEE Sensors Journal 13 (7) : 2521-2522. ScholarBank@NUS Repository. | Abstract: | We propose a simple method for detecting chemical gases using liquid crystal on a planar optical waveguide. Through measuring waveguide output power, this method detects changes in the director of liquid crystal molecules as well as the refractive index, which attributed to gas exposure. We demonstrate this idea by constructing a compact and fast-response ethanol gas sensor. © 2001-2012 IEEE. | Source Title: | IEEE Sensors Journal | URI: | http://scholarbank.nus.edu.sg/handle/10635/89803 | ISSN: | 1530437X |
