Abstract
An optical fiber sensor which comprises a substrate having a groove pattern, an optical fiber which includes a shaped, bare optical fiber portion of an inverted U form and capable of being received or accommodated in the groove pattern of the substrate, and jacketed optical fiber portions extending from the shaped optical fiber rod portion at opposite ends thereof, and an optical modulation unit which is fixedly provided in a light path of the bare optical fiber portion and placed in at least one groove formed in the substrate. A method for fabricating the sensor is also described. The sensors include magnetic filed/current, electric field/voltage and temperature sensors.
