Abstract

All-optical bistability based on injection locked Fabry-Perot semiconductor laser (FP-LD) and its application in all-optical storage are studied in this paper. Injection locking of FP-LD is experimentally studied in this paper. The output power characteristic of injection locked FP-LD is analyzed experimentally, showing that threshold width of hysteresis loop and the extinction-ratio are influenced by the difference in the injection optical-wavelength detuning. Furthermore, 2.5 GHz optical storage with 10 Gb/s input signal is realized by reasonably setting the control signal power. The feasibility of implementing high-speed all-optical storage is verified by using the injection locked FP-LD, which shows great applicability to the field of high speed optical fiber communication.

Optical bistability in side-mode injection locked dual-mode Fabry-Pérot laser diode

Jian Wei Wu, Bikash Nakarmi, Tran Quoc Hoai +1 more

In this paper, optical bistability characteristics are demonstrated experimentally based on a dual-mode laser system comprising a multi-mode Fabry-Pérot laser diode (MMFP-LD) and a built-in feedback cavity formed by a fiber facet. The results show that two lasing modes with frequency separation of ∼0.58 THz and comparable peak powers can be achieved by judicious adjustment of the bias current and the operating temperature of the laser chip, which has a peak fluctuation of less than ∼1 dBm over a measurement period of one hour. A combination of appropriate external injection power and wavelength detuning can result in remarkable optical bistability in two oscillation modes, in which the resulting contrast ratio between the unlocked and locked states can be up to 30 dB, and the corresponding hysteresis loop width can be changed by controlling the side-mode injection power and the wavelength detuning.

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.

We investigate optical bistability of an injection-locked single-mode Fabry-Perot laser diode. Normal and reversed optical bistability curves are observed from the injection-locked laser. And the inverse bistability is used to implement an all-optical flip-flop with the high on-off ratio of over 35 dB.

All-optical flip-flops (AOFFs) using optical bistability of injection-locked Fabry-Perot laser diodes (FP-LDs) are demonstrated. To increase performance of the AOFF, single-mode FP-LDs are introduced. The single-mode FP-LD is used as an auxiliary beam source that sustains the state of AOFF or it is used as a state memory component itself to increase an on-off contrast ratio up to 35 dB.

Optical bistability using a Fabry–Perot semiconductor-laser amplifier with two holding beams

Hitoshi Kawaguchi, Kyo Inoue, Hiroyuki Tani

Bistable switching of an optical signal beam by a control beam with a different wavelength, using the nonlinearity of a Fabry-Perot semiconductor-laser amplifier, is reported for the first time to the authors' knowledge. Depending on the initial detuning of the optical signal beam, both normal (counterclockwise) and reverse (clockwise) hysteresis are theoretically and experimentally obtained in the signal output power as a function of the control input power.
