We present a new evanescent field sensor based on InP/InGaAsP ridge waveguide semiconductor lasers. The laser itself forms an integrated sensing chip containing both a light source and a waveguide. Simple modifications are made to readily available devices, meaning that the chips could form very compact and cost effective sensors.
Key words: biosensor / semiconductor laser / free spectral range
