Abstract
A photoparamp array multiplexer to provide photoparametric amplification in n array of photodiode diodes connected in parallel which essentially eliminates the need for an array of preamplifiers.
Claims2
A photoparamp array multiplexer comprising;
- pump means for outputting pump energy at a predetermined frequency;
- an array of photodiodes connected in parallel and having an input for receiving a modulated light signal, and outputs;
- multiplexing means operatively connected between the output of said pump means and the input to each of said photodiodes;
- demodulating means operatively connected to the outputs of the photodiodes and having an output therefrom corresponding to the output signal of the photodiodes;
- a multiplexing pulse input operatively coupled to said multiplexing means to cause said multiplexing means to couple the output of said pump means to the input of each of said photodiodes one at a time;
- whereby the output of said demodulating means corresponds to the amplified output of an individual photodiode as determined by said multiplexing means.
