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...
The modulation bandwidth of a optical injection-locked (OIL) master-slave configuration using a semiconductor ring laser (SRL) as the slave laser is investigated. The modulation bandwidth depends on the detuning frequency, input optical power into the slave SRL, and the bias current to the SRL in the master-slave configuration. Modulation bandwidth of >40 GHz has been achieved when modulating the...
