摘要

Abstract

Across optics and photonics

excess intensity noise is often considered a liability. Here

we show that excess noise in broadband supercontinuum and superluminescent diode light sources encodes each spectral channel with unique intensity fluctuations

which actually serve a useful purpose. Specifically

we report that excess noise correlations can both characterize the spectral resolution of spectrometers and enable cross-calibration of their wavelengths across a broad bandwidth. Relative to previous methods that use broadband interferometry and narrow linewidth lasers to characterize and calibrate spectrometers

our approach is simple

comprehensive

and rapid enough to be deployed during spectrometer alignment. First

we employ this approach to aid alignment and reduce the depth-dependent degradation of the sensitivity and axial resolution in a spectrometer-based optical coherence tomography (OCT) system

revealing a new outer retinal band. Second

we achieve a pixel-to-pixel correspondence between two otherwise disparate spectrometers

enabling a robust comparison of their respective measurements. Thus

excess intensity noise has useful applications in optics and photonics.
