Coexisting periodic attractors in injection locked diode lasers
نویسندگان
چکیده
We present experimental evidence of coexisting periodic attractors in a semiconductor laser subject to external optical injection. The coexisting attractors appear after the semiconductor laser has undergone a Hopf bifurcation from the locked steady state. We consider the single-mode rate equations and derive a third-order differential equation for the phase of the laser field. We then analyse the bifurcation diagram of the time-periodic states in terms of the frequency detuning and the injection rate and show the existence of multiple periodic attractors.

Underlying dynamics of the pedestal components in a modulated laser diode with noise.
We demonstrate that the pedestal components observed in the power spectra of a directly modulated laser diode, which were interpreted as a sign of instability of the periodic regime, are an indication of the coexistence of a chaotic regime with the periodic one. We present the underlying dynamics behind the rise of these pedestals, showing two different situations in which the pedestals appear....

In this paper we present our recent works on optical injection of Fabry-Perot laser diode for application in access networks. The injection-locked Fabry-Perot laser diode is used as low-cost colorless transmitters for high-speed optical access exploiting wavelength-division-multiplexing technology. The modification of main characteristics of Fabry-Perot laser such as spectral properties, noise ...
متن کاملOptical bistability in diode-laser amplifiers and injection-locked laser diodes.
Static and dynamic properties of dispersive optical bistability (OH) in semiconductor lasers biased from below to above threshold have been investigated theoretically. The OH result is found to be varied continuously from below to above threshold with its maximum value located just above threshold; this result has been verified experimentally. A much faster switch-off of OH can be expected when...

متن کاملInjection - 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...
