Spectral hole-burning observations are critical for practical slow light applications.

Benchmark tests provide standardized evaluation methods for slow light in saturable media.

Abstract

A series of benchmark tests of slow light in saturable absorbers is proposed. Stage I concerns experimental tests of saturable absorption, which can mimic slow light in saturable media. Stage II outlines the more demanding requirements for practical observation of spectral hole-burning in the absorption line, which is responsible for the reduction in group velocity.
