摘要：

A technique is described for extending the resolution of multi-interferometer, guided-wave A/D convertors. Impressing a symmetrical number system (SNS) on the architecture, the optical output waveform for each interferometer is symmetrically folded at a proper modulus. A small comparator ladder mid-level quantises each interferometer output to encode the analogue signal in an SNS format providing resolution greater than 1 bit/interferometer.
