The dynamic properties of DFB- and DML-based injection lock lasers are investigated by analyzing the instantaneous frequency of the master and slave lasers' beat signal. Around 10~20 ns locking time is measured by burst signal injection and a large injection ratio leads to longer unlocking time.
Mode-locked semiconductor lasers are compact pulsed sources with ultra-narrow pulse widths and high repetition-rates. In order to use these sources in real applications, their performance needs to be optimised in several ...
Due to the growing demand for faster Internet connections and the growth of services requiring high bandwidths, the migration of the networks to higher and higher bit rates is inevitable. The surge in data usage due to ...

We theoretically investigate the dynamics of two mutually coupled, identical single-mode semi-conductor lasers. For small separation and large coupling between the lasers, symmetry-broken one-color states are shown to be ...
