Autocorrelation systems for the measurement of picosecond pulses from injection lasers

Abstract
The paper reviews briefly the different structures, alignment techniques and performance of autocorrelation systems for the measurement of picosecond pulses generated by injection lasers suitable for optical communications. The interpretation of results obtained with such systems is also discussed. Specific reference is made to a system operating at 1-3 μm wavelength. The aim is to provide a helpful account of such systems for those starting in the field of picosecond electronics. In order to illustrate the technique some new results are presented on mass-transport injection lasers with low thresholds.
