Optoelectronic fiber photodetector

Patent ·
OSTI ID:1531541

The invention provides an optical fiber photodetector including a photoconductive element, such as a semiconducting element, having a fiber length. The semiconducting element is characterized as a non-composite material in at least one fiber direction. At least one pair of conducting electrodes is in contact with the semiconducting element along the fiber length, and an insulator is provided along the fiber length. An optical resonator can be disposed along the fiber length and along a path of illumination to the semiconducting element. The resonator is dimensioned to substantially reflect all illumination wavelengths except for a prescribed range of wavelengths transmitted to the semiconducting element. The fiber photodetector can be arranged in a photodetecting fiber grid, photodetecting fiber fabric, or other configuration for detecting incident illumination.
