Photogenerator for lightwave networks
First Claim
1. A lightwave system comprising a sending station and a terminal station, at least one optical fiber end connecting the sending station with the terminal station, said optical fiber having an optical beam input end at the sending station and an optical beam output end at the terminal station, a power laser light source at the sending station connected to said at least one optical fiber for launching an optical beam through said optical fiber, an electrically operated apparatus at the terminal station, a photodiode array at the terminal station with the electrical output of the photodiode array connected to said electrically operated apparatus, and means for directing the optical beam from the output end of the optical fiber onto the photodiode array, said photodiode array comprising at least four photodiodes electrically connected in series.

Abstract
The specification describes lightwave systems with remotely powered photoelectric generators. Optical power transmitted through the fiber is incident on a remotely located photodiode array. High power conversion efficiency coupled with a specially designed diode array generates sufficient power to operate electromechanical or electrooptic apparatus in the remote station. Long wavelength photodiodes are serially connected to increase the voltage to practical operating levels. In a communication system, with an optical signal transmitted with the optical power, multiplexers are used for separating the optical power from the optical signal.
