  • Abstract
    A differential measurement scheme using nonlinear optical detection in a silicon avalanche photodiode that was used to measure both the magnitude and sign of the accumulated chromatic dispersion of a stream of laser pulses at 1550 nm is demonstrated. This differential dispersion measurement scheme inherently provides a continuous error signal that was used as feedback to a tunable dispersion compensator so that laser pulses experienced zero net dispersion
