We explore the technique of injection locking a semiconductor laser with a portion of the received optical signal to regenerate a local oscillator for eventual use with a homodyne receiver. In addition, we show that the injection locking process can

We have observed the amplitude magnitude of the modulation of a distributed feedback laser that is injection-locked with an amplitude modulated signal that is tuned across its locking range. We have also demonstrated that this magnitude can be used t

Frequency and intensity modulation characteristics were measured for external cavity GaAs diode lasers as a function of modulation frequency. The data, displayed as a chirp-to-power ratio (CPR), showed at low modulation frequencies a flat response an

The magnitude of the modulation of a DFB laser output that is injection locked with an amplitude modulated signal is measured across its locking range. This magnitude is used to stabilize the locking process.

We have demonstrated that spatial gain modulation in a segmented semiconductor optical amplifier can be converted to a temporal signal. A four-segment amplifier was used to generate digital return-to-zero patterns at 40 Gbits/s , and this technique s

The behavior of the power spectrum of an external cavity semiconductor laser has been studied using a delayed self-heterodyne interferometric technique that uses delay times less than the laser's coherence time. Experimental results show that the res
