Injection - Locked DFB Laser Diode in Main and Multiple Side Modes

One distributed feedback (DFB) laser diode with main and multiple side modes injection-locked is proposed and demonstrated. DFB laser diode can be successfully injection-locked not only in the main mode but also in different side modes. Besides, the side-mode suppression ratio (SMSR) value of each injection-locked mode is enhanced, in which meaning that a new approach suitable for the use of mu...

Theoretical analysis of optical injection locking in semiconductor DFB lasers, influence of the injection direction

Theoretical results concerning injection locking in complex cavity semiconductor lasers are reported. A general equation for the complex temporal envelope of the optical field is derived. The injection direction influence is taken into account and the difference between front and rear phase noise is pointed out and demonstrated. Numerical results are given concerning the feed-in rate of differe...

Analysis of direct-discrimination of FSK modulated optical signal using injection-locked DFB lasers - Optoelectronics [see also IEE Proceedings-Optoelectronics], IEE Proceedings J

Direct discrimination of FM and FSK optical signals using injection-locked DFB semiconductor lasers is analysed. The demodulation eficiency is found to be independent of the optical injection level in the steady state. However, the optical injection level is important in determining the dynamic response. There exists an optimum optical injection rate to achieve the highest demodulation speed. T...

On the Various Time Constants of Wavelength Changes of a DFB Laser Under Direct Modulation

The temporal behavior of the optical frequency emitted by several DFB lasers under direct square wave modulation was measured using an all-fiber implementation of a Mach–Zender interferometer with an imbalance of 30 ps. The impulse response of the optical frequency to injection current modulation was found to contain a time constant as short as 10–20 ns, together with a few longer ones. The exi...
