Metasurface Enhanced Spatial Mode Decomposition [PDF]
Physical Review A, 2022 Abstract Acquiring precise information about the mode content of a laser is critical for multiplexed optical communications, optical imaging with active wave-front control, and quantum-limited interferometric measurements. Hologram-based mode decomposition devices, such as spatial light modulators, allow a fast, direct measurement of the mode ...

Programmable unitary operations for orbital angular momentum encoded states
National Science Open, 2022 We have proposed and demonstrated a scalable and efficient scheme for programmable unitary operations in orbital angular momentum (OAM) domain. Based on matrix decomposition into diagonal and Fourier factors, arbitrary matrix operators can be implemented

Programmable unitary spatial mode manipulation [PDF]
Journal of the Optical Society of America A, 2010 Free space propagation and conventional optical systems such as lenses and mirrors all perform spatial unitary transforms. However, the subset of transforms available through these conventional systems is limited in scope. We present here a unitary programmable mode converter (UPMC) capable of performing any spatial unitary transform of the light field.

Spatial Multiplexing of Whispering Gallery Mode Sensors
Sensors, 2023 Whispering gallery mode resonators have proven to be robust and sensitive platforms for the trace detection of chemical and/or biological analytes. Conventional approaches using serially addressed resonators face challenges in simultaneous multi-channel (

Spatial Extent of Random Laser Modes [PDF]
Physical Review Letters, 2007 We have experimentally studied the distribution of the spatial extent of modes, and the crossover from essentially single-mode to distinctly multi-mode behavior inside a porous gallium phosphide random laser. This system serves as a paragon for random lasers due to its exemplary high index contrast. In the multi-mode regime we observed mode competition.

Spatial-mode-demultiplexing for enhanced intensity and distance measurement
, 2022 Spatial-mode demultiplexing (SPADE) has recently been adopted to measure the separation in the transverse plane between two incoherent point-like sources.
