A surface plasmon resonance sensor apparatus includes a common substrate, a surface emitting laser, such as a VCSEL, arranged on the common substrate, a sensor array, such as CCD array, arranged on the common substrate, a light-transmitting medium provided above the common substrate, and a metal thin film formed on the light-transmitting medium to cause surface plasmon resonance due to light which is emitted from the surface emitting laser, transmitted through the light-transmitting medium and impinging on the metal thin film. The surface emitting laser, metal thin film and sensor array are positioned such that a change in an intensity of light reflected by the metal thin film caused by the surface plasmon resonance can be measured by the sensor array.

1. A surface plasmon resonance sensor apparatus comprising:(a) a common substrate; (b) a sensor array arranged in a predetermined direction and spaced on said common substrate; (c) a light-transmitting medium spaced above said common substrate; (d) a metal thin film formed on said light-transmitting medium; (e) a surface emitting laser spaced on said common substrate adapted to emit light through said light-transmitting medium to be reflected from said metal thin film and simultaneously generate a surface plasmon resonance sufficient to change intensity of light reflected from said metal thin film such that light emitted from said surface emitting laser is polarized in said predetermined direction without use of a polarizer, wherein the light emission point of the surface-emitting laser is elliptically shaped; and (f) an optical element positioned between said surface emitting laser and said metal thin film for spreading the light emitted from said surface emitting laser in said predetermined direction; wherein said surface emitting laser, said metal thin film and said sensor array are positioned to measure the intensity of the light reflected by said metal thin film.
