Frequency domain bistability of tunable laser with frequency-dependent feedback

Lixue Chen

Traditional frequency domain optical bistability(FDOB) devices with hybrid electro-optical feedback have low response speed and high noise fluctuations.Hence,a novel tunable laser FDOB device with an all-optical feedback was developed using a nonlinear fiber ring resonator as the frequency feedback element.Parametric equations of optical bistability were established according to the system's response to nonlinear process and frequency-dependent feedback.Based on the parametric equations,the characteristics and controllable operations of FDOB were analyzed.The switching response speed of the optical bistability was discussed.The analysis showed that the proposed all-fiber laser bistability device can effectively achieve intensity-driven and gain-driven optical bistability.The position and shape of the bistability hysteresis curve vary with the adjustment of gain or loss in the fiber ring resonator,hence realizing the controlled all-optical bistability operations.Sudden jumping of optical bistability in the frequency domain can be applied to monitor laser wavelength shift and achieve sensoring.The optical bistability response time is in the nanosecond order of magnitude and bistability switching is ultrafast.

We observe a novel hybrid optical bistability by using an electro-optically tuned cw fibre laser with a fibre Fabry–Perot filter. The principles of the optical bistable device in two operation manners are analysed. The applications in monitoring the wavelength shift of a tunable fibre laser and fibre sensor of digital type are also discussed.

We propose a novel optical bistable device (OBD) in frequency-domain with which we can perform optical bistable operations in a number of fibre Bragg gratings (FBGs) which are included in the same OBD. Such an OBD may bring more opportunities in applications and, as an example, we show the possibility of using it in an FBG sensor demodulating system. By use of a tunable light source, consisting of a broad band source and a scanning fibre F–P (FFP), we demonstrate the above-mentioned operations experimentally.

Fiber-ring laser with tunable optical bistability

Jiafeng Shao, Qin Shen, Z. J. Wu +3 more

The structure of combining two segments of erbium-doped fiber (EDF) together—one EDF acting as an amplifier and the other as an absorber—has a special gain characteristic curve which has a maximum gain with an increase in the input signal power. This special gain characteristic curve can lead to an optical bistability (OB) phenomenon in a fiber-ring laser employing an EDF of this structure. By adjusting the pump light power injected into the second segment of the EDF, we can change the behavior of the absorber and can, therefore, control the range of the bistability region. A method is proposed to calculate the tunable optical bistability, and the calculation result is in accordance with our experiment.
