    Abstract:

    We report on the generation of Short Optical Pulses by utilizing the non-linear absorption characteristics of a multiple quantum well (MQW) electro-absorption modulator, which is monolithically integrated with a MQW wavelength-tunable distributed Bragg reflector (DBR) laser on a single chip. Optical Pulses as Short as 39 ps and 15 ps have been generated at a repetition rate of 3 GHz and 10 GHz, respectively, with a broad tuning range of 5.4 nm near 1554 nm lasing wavelength.© (1994) COPYRIGHT SPIE--The International Society for Optical Engineering.

  • Characterization of Gain-Switched Pulses From 1.55-$\mu$m VCSEL
    IEEE Photonics Technology Letters, 2010
    Co-Authors: Antonio Consoli, I. Esquivias, F. Lopez J. Hernandez, J. Mulet, Salvador Balle
    Abstract:

    We report on Short Optical Pulse generation by gain-switching (GS) a low-cost commercial vertical-cavity surface-emitting laser emitting at 1.55 μm. The dependence of Pulse characteristics on GS parameters is investigated and analyzed. Pulses with duration of 55 ps and time-bandwidth product between 0.91 and 2.2 are obtained at repetition rates between 1 and 3 GHz.

  • spectral phase encoding of ultra Short Optical Pulse in time domain for ocdma application
    Optics Express, 2007
    Co-Authors: Xu Wang, Naoya Wada
    Abstract:

    We propose a novel reconfigurable time domain spectral phase encoding (SPE) scheme for coherent Optical code-division-multiple-access application. In the proposed scheme, the ultra-Short Optical Pulse is stretched by dispersive device and the SPE is done in time domain using high speed phase modulator. The time domain SPE scheme is robust to wavelength drift of the light source and is very flexible and compatible with the fiber Optical system. Proof-of-principle experiments of encoding with 16-chip, 20 GHz/chip binary-phase-shift-keying codes and 1.25 Gbps data transmission have been successfully demonstrated together with an arrayed-wave-guide decoder.

  • A Novel Highly Stable Dual-Wavelength Short Optical Pulse Source Based on a Dual-Loop Optoelectronic Oscillator With Two Wavelengths
    IEEE Photonics Journal, 2015
    Co-Authors: Jinlong Yu, Zixiong Wang, Ju Wang, Wenrui Wang, Bin Chen, Yang Yu
    Abstract:

    A novel scheme of a highly stable dual-wavelength Short Optical Pulse source (SOPS) based on a dual-loop optoelectronic oscillator (OEO) with two wavelengths is demonstrated. The structure of the dual-loop OEO with two wavelengths can suppress the random beating noise effectively and generate the microwave signal with low phase noise (-122.4 dBc/Hz at 10 kHz) . It consists of two directly modulated lasers and a phase modulator (PM) . The light that is directly modulated by the large signal generated from the OEO is injected into the PM to achieve remarkable chirp. Then, by optimizing the length of the dispersion compensating fiber, the Optical Pulses are further compressed. In the experiment, the SOPS with dual wavelengths is generated simultaneously. The repetition rate, Pulse width, and timing jitter of the SOPS are 10 GHz, 2.9 ps, and 12.5 fs, respectively. In particular, the loop drift of the OEO is effectively compensated by fiber stretchers using phase-locked-loop technology. The frequency drift of the microwave signal is less than ±73.3 mHz for a long-term measurement with a duration of 1 h. Therefore, the long-term stability of SOPS is guaranteed.

  • The Improvement of Fiber Parametric Amplifier Pulse Source via Phase Modulation of Pump Light
    2011 International Conference on Control Automation and Systems Engineering (CASE), 2011
    Co-Authors: Xiaoyuan Zhang, Jinlong Yu
    Abstract:

    A novel scheme on the improvement in Short Pulse generation is studied based on phase modulator and fiber Optical parametric amplifier (FOPA). The continuous-wave (CW) pump light was first sinusoidally intensity modulated, and then modulated by an electro-optic phase modulator in which the nonlinear chirp and undesirable negative chirp components were sufficiently restrained. The modulated light was compressed into Shorter Pulse by a dispersion media. It was confirmed by the experiment that 12.7-ps Short Optical Pulse with high extinction ratio can be generated in this way.

  • phase modulator based optoelectronic oscillator for generating Short Optical Pulse and microwave signal
    Optical Engineering, 2007
    Co-Authors: Yang Jiang, Jinlong Yu, Wenrui Wang, Hao Hu, Yaotian Wang, Enze Yang
    Abstract:

    A phase-modulator-based optoelectronic oscillator (OEO) is utilized to implement a self-starting Optical Pulse and microwave signal source. This system is able to simultaneously generate a 9.8-GHz Optical Pulse stream with 141-fs (over 100 Hz to 1 MHz) timing jitter and 6.5-ps Pulse width, along with a high spectral purity electrical signal that is locked to the repetition rate of the Optical Pulses. The measured phase noise is −112 dBc/Hz at 10 kHz away from carrier, and the side modes are perfectly suppressed.

  • 20 GHz ultra-Short Optical Pulse source generated by DFB-LD and Pulse compression technology
    Canadian Conference on Electrical and Computer Engineering 2001. Conference Proceedings (Cat. No.01TH8555), 2001
    Co-Authors: Jinlong Yu, Enze Yang
    Abstract:

    This paper studies that generation of 20 GHz ultra-Short Optical Pulse series by 10 GHz DFB-LD with OTDM and Pulse compression technology. A novel three-stage compression technology is brought forward, including compensation in normal dispersion fiber, compressing in anomalous dispersion fiber followed normal dispersion fiber and in comb-like dispersion profile fiber (CDPF). In the experiment, the compressed Pulse of 3.3 ps Pulse width was obtained and the total compress factor is 7.6. This technique is important for implementing an 80 Gb/s OTDM system.
