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.…
Sensing with Twisted Light: Precision Measurement of Fractional Azimuthal Index to Determine Refractive Index
Christopher Perrella, Aman Anil Punse, Anastasiia Zalogina +6
Light beams possessing orbital angular momentum (OAM) have gained significant interest in areas such as optical manipulation, quantum entanglement, and super-resolved imaging. In i…
The Radiation Pressure of Light: historical perspectives and the role of structured light
Alexander C. Trowbridge, Ewan M. Wright, Kishan Dholakia
Light, or electromagnetic radiation, is well known to possess momentum, and the exchange of this momentum with a reflecting surface leads to radiation pressure. More often than not…
Optical Manipulation of Whispering Gallery Mode Microlasers for Precision Controlled Cellular Delivery
Soraya Caixeiro, Paloma Rodríguez-Sevilla, Kishan Dholakia +1
Whispering gallery mode microlasers are known for their high Q-factors, characteristic emission spectra and sensitivity to local refractive index changes. This sensitivity combined…
