Abstract :
Semiconductor ring laser (SRL) is a promising device for integrated optical injection locking (OIL) configuration, as the SRL operates only in the direction receiving injection, therefore does not feedback into the master laser. We have successfully demonstrated for the first time significant enhancement in the modulation bandwidth of OIL-SRL to >20GHz which limited our measurement bandwidth. The tunable laser is modulated using a Mach-Zehnder modulator (MZM) by the RF signal generated by the vectorial network analyser (VNA).
