Abstract : The present invention is directed to pump multiplexing circuits which use a single local oscillator, a multiplexer and a single synchronous demodulator to transform an array of photodiodes into an array of photoparametric amplifiers. Use of the photoparamp array multiplexer provides an advantage for large arrays of photodiodes because it essentially eliminates the need for an array of preamplifiers associated with the photodiodes. The technique also offers a potential increase in sensitivity since photoparametric amplification is essentially a noiseless process.
