“…18 To date, many techniques have been proposed and experimentally demonstrated to successfully produce dual-mode lasing operation, [19][20][21][22][23][24] and among these, multi-mode Fabry-Pérot laser diode (MMFP-LD) based devices are worthy of extensive investigation because of their rich variety of nonlinear phenomena, cost effectiveness, low power consumption and low threshold current. [25][26][27] In general, the MMFP-LDs associated with external cavity feedback and incorporating fiber Bragg gratings and tunable filters were often chosen for selection of special feedback wavelengths that are then fed back into the active region to produce dual-mode laser oscillation in the output spectrum. These previously presented techniques undoubtedly have some distinct advantages and some limitations in terms of optical signal processing.…”

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.

“…A wideband bias-tee (Mini-circuits, ZX85-12G-S+) was used to couple the DC bias and the modulating data for driving the WRC-FPLD. The WRC-FPLD was directly modulated by a 10-Gbit/s NRZ-OOK data generated form a pattern generator (Agilent, 70843B) with a pattern length of 2 23 À 1. The operating DC bias was set at two times of the threshold current ðI th Þ and the peak-to-peak amplitude of the electrical 10-Gbit/s NRZ-OOK data was set at 1.3 V.…”

A coherently injection-locked and beyond-bandwidth-modulated weakresonant-cavity laser diode (WRC-FPLD) transmitter packaged by a conventional TO-56 can package for an upstream 10-Gb/s OOK transmission is demonstrated in a DWDM-PON. With specific temperature controlling, the WRC-FPLD is able to maintain its temperature during the process of injection locking. Based on the theoretical analysis of modified rate equations, the injection-locked WRC-FPLD exhibits not only a broadband gain spectrum but also a large modulation bandwidth. Successfully implementing injection locking enhances the high-frequency throughput response but inevitably impairs the throughput intensity at a low-frequency region. By properly increasing the injectionlocking power, the modulation bandwidth of the injection-locked WRC-FPLD can be further improved. In addition, the extinction ratio and the signal-to-noise ratio (SNR) of the transmitted 10-Gb/s NRZ-OOK data can also be improved from 5.58 to 6.95 dB and from 5.43 to 6.18, respectively, by increasing the injection-locking power from À12 to À3 dBm, which improves the receiving power sensitivity by 1.6 dB. The optimized receiving power sensitivity at a requested bit error rate (BER) of 10 À9 is À15.4 dBm by setting the injection-locking power at À3 dBm. After a 25-km transmission, such an overbandwidth-modulated and injection-locked WRC-FPLD reveals a receiving power sensitivity of À11.6 dBm at the same BER of 10 À9 .

The lasing wavelength shift characteristics of amplified spontaneous emission (ASE)‐injected wavelength‐locked Fabry‐Perot laser‐diodes used in the wavelength division multiplexed passive optical network are studied. The lasing wavelength shift at different injected‐ASE powers and different bias currents are experimentally evaluated. The saturation effect has been found as the bias current increases. © 2011 Wiley Periodicals, Inc. Microwave Opt Technol Lett, 2011; View this article online at wileyonlinelibrary.com.
