Autor: Bruce, Graham D., O'Donnell, Laura, Chen, Mingzhou, Facchin, Morgan, Dholakia, Kishan

Publikováno v: Opt. Lett. 45, 1926-1929 (2020)

Many areas of optical science require an accurate measurement of optical spectra. Devices based on laser speckle promise compact wavelength measurement, with attometer-level sensitivity demonstrated for single wavelength laser fields. The measurement

Overcoming the speckle correlation limit to achieve a fiber wavemeter with attometer resolution

Autor: Bruce, Graham D., O'Donnell, Laura, Chen, Mingzhou, Dholakia, Kishan

Publikováno v: Optics Letters 44, 1367-1370 (2019)

The measurement of the wavelength of light using speckle is a promising tool for the realization of compact and precise wavemeters and spectrometers. However, the resolution of these devices is limited by strong correlations between the speckle patte

Report

High speed determination of laser wavelength using Poincar\'e descriptors of speckle

Autor: O'Donnell, Laura, Dholakia, Kishan, Bruce, Graham D.

Publikováno v: Optics Communications 459, 124906 (2020)

Laser speckle can provide a powerful tool that may be used for metrology, for example measurements of the incident laser wavelength with a resolution beyond that which may be achieved in a commercial device. However, to realise highest resolution req
