Phase Sensitivity of Spectrally Multimode SU(1,1) Interferometers with Waveguide based Optical Parametric Amplifier
Sonu Jana, Swagatam Bag, Fabien Bretenaker +2
We present a comprehensive framework for evaluating the phase sensitivity of spectrally multimode SU(1,1) interferometers probed with a coherent-vacuum input, under both number and…

Sensitivity Evaluation of SU(1,1) Interferometers with Arbitrary Input Probe State and Homodyne Detections
Sonu Jana, Dhruv Baheti, Paul Grossiord +3
We provide a general theoretical derivation of the phase sensitivity achieved by SU(1,1) interferometers under homodyne detection. The general expressions obtained accommodate arbi…
