Correlation Revival Eigenmodes for Differential Sensitivity in Speckle Metrology
Hal Gee, Morgan Facchin, Graham D. Bruce
Speckle metrology exploits the high sensitivity of scattered fields to parameters of interest, yet this also leaves measurements vulnerable to unintended perturbations. Here we emp…
Ultra-high precision speckle spectrometer enabling radio-frequency scale resolution of atomic spectra
Gabriel Britto Monteiro, Christopher Perrella, Sarah K. Scholten +4
Laser speckle, the granular intensity pattern arising from random optical interference, provides a high-dimensional encoding of spectral information that can be exploited for preci…
Through-bottle spectroscopy as a tool for quality control and anti-counterfeiting of Brandy and Cognac
George O. Dwapanyin, Edward I. Appleton, Stella Corsetti +4
Counterfeiting of premium spirits poses significant economic and health risks, that could be tackled by robust, accurate, portable and non-destructive through-bottle measurements.…
Performance limit of on-chip speckle spectrometers
Bhupesh Kumar, Graham D. Bruce, Luca Dal Negro +1
Disorder-driven, integrated speckle spectrometers offer exceptional spectral resolution within a compact design. They benefit from enhanced optical path lengths due to multiple lig…
All-optical sub-Kelvin sympathetic cooling of a levitated microsphere in vacuum
Yoshihiko Arita, Graham D. Bruce, Ewan M. Wright +3
We demonstrate all-optical sympathetic cooling of a laser-trapped microsphere to sub-Kelvin temperatures, mediate by optical binding to a feedback-cooled adjacent particle. Our stu…
Cooling the optical-spin driven limit cycle oscillations of a levitated gyroscope
Yoshihiko Arita, Stephen H. Simpson, Graham D. Bruce +3
The non-conservative, azimuthal forces associated with inhomogeneous optical-spin angular momentum play a critical role in optical trapping. Intriguingly, birefringent microspheres…
