Spectral and Time Phenomena in Optical Injection Using Distributed Feedback Semiconductor or Fiber Lasers

Résumé

Optical injection is compared for distributed feedback semiconductor and fibre lasers whose wavelength is around 1550 nm. A spectral description of an injected semiconductor laser is presented for usual injected power (> 30 dBm), by mapping out several phenomena, such as bistable areas, undamped relaxation and chaos synchronization. For weak injection levels (< 30 dBm), the slave acts as a highquality amplifier of spectrally narrow signals. In this case, the slave frequency is pulled by the master one. Theory of weak injection is demonstrated using a generalized Airy's function method. We also present the temporal response of a fibre laser output power for static injection, and observe original dynamics linked to relaxation processes. A new method using optical injection is proposed to measure narrow linewidth or spontaneous emission rate.
