Abstract :
A silicon-on-insulator based evanescent field sensor using silicon photonic wire waveguides is reported. The unique properties of high index contrast, submicron structures are exploited to enhance electric field magnitude and localization near the sensor surface. The evanescent field sensor is demonstrated in a Mach Zehnder configuration.
