The PCW is based on widely used lithographic and nano-fabrication compatible materials like TiO 2 and SiO 2. Gold has been used as a SPR active metal. Employing coupled mode theory, the sensitivity is found to be as high as ? 66 pm/K. � 2011 Copyright Society of Photo-Optical Instrumentation Engineers (SPIE).enSurface plasmon resonanceTemperature sensorWaveguidesConference Paper
