- Title: Reconfigurable phase contrast microscopy with correlated photon pairs
- Authors: Hazel Hodgson, Yingwen Zhang, Duncan England, Benjamin Sussman
- Abstract summary: A phase-sensitive microscopy technique is proposed and demonstrated that employs the momentum correlations inherent in spontaneous parametric down-conversion.
One photon from a correlated pair is focused onto a microscopic target while the other is measured in the Fourier plane.
This provides knowledge of the position and angle of illumination for every photon striking the target, allowing full post-production control of the illumination angle used to form an image.

- Abstract: A phase-sensitive microscopy technique is proposed and demonstrated that
employs the momentum correlations inherent in spontaneous parametric
down-conversion. One photon from a correlated pair is focused onto a
microscopic target while the other is measured in the Fourier plane. This
provides knowledge of the position and angle of illumination for every photon
striking the target, allowing full post-production control of the illumination
angle used to form an image. The versatility of this approach is showcased with
asymmetric illumination and differential phase contrast imaging, without any
beam blocks or moving parts.

We introduce a quantum-based quantitative phase microscopy technique using a phase gradient approach.
We show that the technique, while achieving an imaging resolution of 2.76,$mu$m, is phase accurate to at least $lambda/30$ and phase sensitive to $lambda/100$ at a wavelength of 810,nm.

down-conversion with varying focal planes of interacting beams [0.0]
Spontaneous parametric down-conversion (SPDC) is a widely used process to prepare entangled photon pairs.
The exact focal plane position of the pump beam relative to those of the detection modes is difficult to determine in a real experiment.
In this work, we consider variable positions of focal planes and investigate how shifts of these focal planes influence the spatial and temporal properties of photon pairs.

We study a system of two interacting, non-indentical quantum emitters driven by a coherent field.
We show that the features imprinted by the two-photon dynamics into the spectrum of resonance fluorescence are particularly sensitive to changes in the distance between emitters.
This can be exploited for applications such as superresolution imaging of point-like sources.
