Zusammenfassung:In this invention, a transmissive optical detector for low loss monitoring of transmitted optical power is described. The optical detector consists of a partially absorbing coating whose electrical characteristics change under illumination while letting most of the optical power pass through unperturbed. The coating is, for example, a transparent conductor such as indium tin oxide coated on the endface of a fiberoptic waveguide.
