Programmable unitary spatial mode manipulation
Jean-Francois Morizur,Lachlan Nicholls,Pu Jian,Seiji Armstrong,Nicolas Treps,Boris Hage,Magnus T. L. Hsu,Warwick P. Bowen,Jiri Janousek,Hans-A. Bachor +9 more
TL;DR: This work builds an experimental implementation of the unitary programmable mode converter (UPMC) and shows that, even when limited to three reflections on an array of 12 pixels, the UPMC is capable of performing single mode tranforms with an efficiency greater than 80% for the first four modes of the transverse electromagnetic basis.
Journal ArticleDOI
Optimal optical measurement of small displacements
TL;DR: In this article, the authors derived the quantum noise limit for the optical beam displacement of a TEM00 mode using a multimodal analysis, and showed that the conventional split detection scheme for measuring beam displacement is non-optimal with ~80% efficiency.
Journal ArticleDOI
Quantum study of information delay in electromagnetically induced transparency.

TL;DR: It is shown that the EIT system adds excess noise to the delayed light that has not hitherto been predicted by published theoretical modeling.
Journal ArticleDOI
Optimum Small Optical Beam Displacement Measurement
TL;DR: In this article, the authors derived the quantum noise limit for the optical beam displacement of a TEM00 mode using a multimodal analysis and showed that the conventional split detection scheme for measuring beam displacement is non-optimal with 80% efficiency.
Journal ArticleDOI
Nano-displacement measurements using spatially multimode squeezed light
Nicolas Treps,Nicolas Treps,Nicolai Grosse,Warwick P. Bowen,Magnus T. L. Hsu,Agnès Maître,Claude Fabre,Hans-A. Bachor,Ping Koy Lam +8 more
TL;DR: In this paper, a lossless combination of these modes can be achieved using the non-degenerate Gouy phase shift of optical resonators, and the combined squeezed beams are measured with quadrant detectors.
