| 标题： Semiconductor Quantum-Dash Mode-locked Lasers in Terabits/s Optical Communication and 5G & beyond Wireless Network Applications | |
| 摘要： Semiconductor-based monolithic mode-locked lasers (MLLs) with their ability to emit extremely stable, ultra-narrow and low noise optical pulse trains at high repetition rate are a promising technology for multi wavelength optical sources application in state of the art coherent optical communications and 5G & beyond wireless networks in millimeter-wave (mmW) bandwidths, in order to achieve ultrahigh data capacity and overcome the spectrum crunch [1]. Other advantages include compact size, low power consumption, low cost, simple fabrication, and the ability for hybrid integration with silicon substrates. MLLs utilizing quantum dots or dashes (QD) rather than quantum wells are particularly attractive due to the reduced amount of amplified spontaneous emission leading to lower intrinsic noise, narrower linewidth, and hence ultra-low timing jitter [2, 3]. We have previously demonstrated InAs/InP QD MLLs with various pulse repetition rates and a total output power up to 50 mW per facet at room temperature [4, 5]. In this presentation, we demonstrate InAs/InP C-band QD fabry-perot (passive) mode-locked lasers with extremely low RIN, phase noise, and ultra-low timing jitter developed in National Research Council Canada and their applications in coherent optical communication [6] and wireless networks [7] in the following sections: 1. Introduction 2. Theory 3. Material grown and device fabrication 4. Laser performance characterizations, such as LIV, RIN, phase noise and timing jitter. 5. Demonstrations of by using only a NRC QD MML achieved > 10 terabits/s data capacity with a double-polarization high order quadrature amplitude modulation (QAM) optical system through 100-km standard single mode fiber transmission. 6. Demonstrations of a millimeter-wave photonic-aided-radio-over-fiber broadband wireless networking system using only one NRC QD MML to replace over 60 conventional individual DFB lasers. 7. Conclusion 8. Acknowledgment: This work was supported by the High Throughput and Secure Networks (HTSN) Challenge Program at the National Research Council of Canada. Reference [1] Z.G. Lu, J.R.
