An integrated optical waveguide type surface plasmon resonance (SPR) sensor having an optical waveguide with a corresponding SPR sensing area, photodetectors, and wavelength tunable laser or any kind of tunable laser source/coupler formed on a substrate. In an embodiment, the laser is a wavelength tunable laser and optionally, the integrated device may include a power source on the substrate for providing an electric power to the wavelength tunable laser and the photodetectors, or a circuit for signal coupling, or a microfluidic structure for routing a target sample to the SPR sensor area. The microfluidic structure optionally includes a mixer or a reaction chamber for mixing and allowaing a physical or chemical reaction to occur, respectively. In an embodiment, plural planal integrated optical waveguide type SPR sensors may be fabricated on a substrate to form an array of SPR sensors.
