Statistical optics
TLDR
Development of this more comprehensive model of the behavior of light draws upon the use of tools traditionally available to the electrical engineer, such as linear system theory and the theory of stochastic processes.Abstract:
Course Description This is an advanced course in which we explore the field of Statistical Optics. Topics covered include such subjects as the statistical properties of natural (thermal) and laser light, spatial and temporal coherence, effects of partial coherence on optical imaging instruments, effects on imaging due to randomly inhomogeneous media, and a statistical treatment of the detection of light. Development of this more comprehensive model of the behavior of light draws upon the use of tools traditionally available to the electrical engineer, such as linear system theory and the theory of stochastic processes.read more

Superabsorption of light via quantum engineering
Kieran D. B. Higgins,Simon C. Benjamin,Thomas M. Stace,Gerard J. Milburn,Brendon W. Lovett,Erik M. Gauger +5 more
TL;DR: This work shows that superabsorption can be achieved and sustained in certain simple nanostructures, by trapping the system in a highly excited state through transition rate engineering, which opens the prospect of a new class of quantum nanotechnology with potential applications including photon detection and light-based power transmission.

Sculpturing the electron wave function using nanoscale phase masks.
TL;DR: A method in electron-optics for arbitrarily shaping electron beams into a single desired shape, by precise patterning of a thin-membrane, allowing for nearly-maximal energy transference to the designed shape, and may avoid physical damage and charging effects that are the scorn of commonly-used phase-plates.

Second harmonic generation imaging as a potential tool for staging pregnancy and predicting preterm birth
TL;DR: The ability to quantify multiple morphological features of collagen that characterize normal cervical remodeling and distinguish abnormal remodeling in preterm birth models supports future studies aimed at development of SHG endoscopic devices for clinical assessment of collagen changes during pregnancy in women.
