Optical signal to noise ratio monitoring using single channel sampling technique
Optics Express, 2014 In this paper, we propose a novel method to depict 2-dimension (2-D) phase portrait by using single-channel-sampling (SCS) technique, which can be used for optical performance monitoring. Single low speed sampling scheme reduces cost and complexity of monitoring system setup significantly.

Detection of amplitude modulation with squeezed light for sensitivity beyond the shot-noise limit [PDF]
, 1988 An improvement in precision beyond the limit set by the vacuum-state or zero-point fluctuations of the electromagnetic field is reported for the detection of amplitude modulation encoded on a weak signal beam. The improvement is achieved by employing the
