The phase sensitivity of a fully quantum three-mode nonlinear interferometer

2018 · New Journal of Physics

We study a nonlinear interferometer consisting of two consecutive parametric amplifiers, where all three optical fields (pump, signal and idler) are treated quantum mechanically, allowing for pump depletion and other quantum phenomena. The interaction of …

Unitary linear optical transformations in a reconfigurable platform

2020 · Frontiers in Optics / Laser Science

Applications across photonics require transformations of optical spatial modes. Utilizing a discrete set of phase masks and free space propagation, we experimentally demonstrate general transformations on a beam array.
