PROBLEM TO BE SOLVED: To provide a sensor which performs detection by a compactly integrated device with high sensitivity and the sensor freely placed at a desired position in a flow channel in the field of microchemical/biochemical analysis using a micro flow channel. SOLUTION: The sensor is a measuring apparatus which detects information and outputs an optical output according to the information. The sensor comprises an active layer which emits light and a micro optical resonator. Photoelectro-magnetic field mode selection by the micro optical resonator influences the active layer to restrict the light emission, resulting in spatially selective light emission. The degree of the photoelectro-magnetic field mode selection changes according to the environmental conditions around the micro optical resonator, leading to changes in the light emission. Based on the changes in the light emission, the environmental conditions are measured. COPYRIGHT: (C)2004,JPO
