26 December 1984 Observation Of Light Detection By Glass-Metal Seals: The Possibility Of Optical-Fiber Light Detectors
Author Affiliations +
Ordinary glass-metal seals are reported here to give rise to currents as a result of light illumination. Responsivity observed here is of the order of 10 mA.W . Signal-polarity results suggest that the seal acts as a Schottky barrier. Photoionization of impurities, particularly iron oxide, in the glass energy gap is believed to be the detection mechanism. A method is suggested for increasing responsivity. Development of glass optical detectors may be advantageous for many applications involving optics and glass, including integrated optics, particularly in view of the low cost, the negligible dark current, and the guiding capabilities of glass fibers. The detection properties of glass-metal seals should be considered when evaluating experimental results, such as the optogalvanic effect, involving discharges as detectors of light.
