BIBLIOGRAPHY

Describes standard procedures for measuring time-resolved chirp on laser transmitters. Also specifies means to verify the TRC setups and calculations and a review of laser modulation methods and the relationship of TRC to performance in a transmission system.

Provides procedures for measuring time-resolved chirp on laser transmitters. The calculation of alpha-factor, a measure of transient chirp, is derived from the measured TRC data. A means to verify the TRC setups and calculations and a review of laser modulation methods and the relationship of TRC to performance in a transmission system are also coverd.
