Pulse position Instability in injection lasers

Abstract

A new form of optical Instability in semiconductor-injection lasers is reported in which the position of the optical pulse, generated by a gain switched laser, can take one of two stable positions within a clock cycle. Unlike some forms of optical bistability,1–3 the contrast ratio between the light levels for the two states is high (>20 dB). The optical power required to trigger from one state to the other is typically a few percent of the laser output power, and the duration of the trigger pulse needs be only a fraction of the clock cycle. Trigger energies can, therefore, be in the femtojoule range. Both electrical and optical trigger mechanisms are discussed.

Gigabit pulse position bistability in semiconductor lasers

Dominic F. G. Gallagher, Ian H. White, J.E. Carroll +1 more

The paper briefly reviews the major forms of optical bistability in active optical devices compatible for use in gigabit optical communication systems, and reports an entirely new optical bistability for the first time. Unlike previous devices, the two bistable states of the optical device are each a series of picosecond optical pulses at 1 GHz or greater repetition rates, and are distinguished by a half period temporal shift between their temporal positions in relation to a clock pulse. The bistable device is based on a gain switched semiconductor laser. Theoretical studies suggest 100-ps switching speeds might be achieved, and experimental results are reported indicating optically triggered switching times of 500 ps.

Optical frequency bistability and power bistability in semiconductor lasers

Linlin Li

Optical frequency bistability and power bistability in semiconductor lasers biased from below to above threshold are presented using the unified description of semiconductor lasers with external light injection. A new method is given to calculate the bistable frequency and power loop widths. When the bias current of a laser is fixed, there is a lowest power for the external light to realize optical frequency bistability. And this lowest power reaches its minimum just at threshold. The optical injection level (defined as the ratio of the injected power to the power emitted by the free-running laser) must be larger than a certain value to obtain the bistability. This level may be larger than unity for a laser biased below threshold. On the other hand, for a given bias current, there is a lowest frequency detuning between the electric field of the laser and the injected field to achieve the power bistability. And this detuning must be negative for any bias current (below or above threshold) of the laser. The results are in good agreement with experiments.>

Comparison of switching times in optically bistable injection-locked semiconductor lasers

Marko M. Krstić, Jasna V. Crnjanski, Angelina R. Totovic +1 more

In this paper, on the basis of the derived analytical model, we analyze switching between stable states of the optically bistable injection-locked semiconductor Fabry–Perot laser. We investigate three different mechanisms of switching: injection power, frequency detuning and bias current variation, and compare switching times obtained for these switching mechanisms.

Reconfigurable all-optical bistability/tristability in dual injection-locked Fabry–Perot laser diodes

Mladen Ž. Banović, Petar A. Atanasijević, Marko M. Krstić +4 more

In this Letter, we present a detailed theoretical and experimental investigation of optical bistability and tristability in dual injection-locked Fabry-Perot laser diodes. The proposed device can be reconfigured between the bistable and tristable regimes, simply by adjusting the power level of the injected control optical signal. The tristability presented in the experiment is achieved for relatively low optical input powers between 1.03 and 1.25 mW, with the output signal ratio of up to 7 dB between stable states. Such a device is a potential candidate for designing trits, a bit analogy in ternary computational logic.

Optical polarization bistability in TM wave injected semiconductor lasers

Yoshihiro Mori, J. Shibati, Takao Kajiwara

Experimental results of optical polarization bistability in InGaAsP lasers are reported and the causes of polarization switching and nonlinear response in this bistability are discussed. The input light signal consisted of the transverse magnetic (TM) wave, while the semiconductor lasers operated in a fundamental transverse electric (TE) mode when the light input was not injected. The light output versus light input characteristics were dependent on the input wavelength. Switching times of up to a few hundred picoseconds were achieved for both switch-up and switch-down. It was found that the TE and TM outputs originate from the TE oscillation and the TM amplification, respectively. Calculations using the rate equations showed that the TM input induces the nonlinearity of the carrier density. These results indicate that this bistability is a type of dispersive bistability.>

Dynamic properties of transverse-magnetic wave injected semiconductor lasers

Yoshihiro Mori

Dynamic responses of optical polarization bistability and self-sustained pulsation in transverse-magnetic (TM) wave injected semiconductor lasers are analyzed. Due to the TM wave injection, laser amplification of TM wave and laser oscillation in the transverse-electric (TE) mode simultaneously occurs in the laser. The calculated dynamic responses of optical polarization bistability are compared with measured responses. The upper limit of the switching time and the repetition frequency are clarified from calculations. The self-sustained pulsation triggered by a change of TM input power is found in the course of the calculation. The conditions needed for the pulsation are discussed.>
