Numerical Analysis for High-Speed Hybrid- Modulation Semiconductor Laser Integrated With Passive Waveguide
The high-speed intrinsic modulation characteristics of a hybrid-modulation laser diode integrated with a passive waveguide was numerically analyzed. It was confirmed that the 3-dB intrinsic small-signal modulation bandwidth depended on the coupling coefficient of the corrugation grating
$\kappa $
at the distributed feedback (DFB) section and modulation amplitude ration (MAR) at the DFB and intra-cavity loss-modulation sections. The modulation bandwidth became wider when
$\kappa $
decreased and MAR increased. The maximum 3-dB E/O modulation bandwidth was more than 600 GHz when
$\kappa $
and MAR were from 40 to 80 cm−1 and 6.4 V. It remained more than 300 GHz when
$\kappa $
was from 40 to 200 cm−1 and MAR was from 3.2 to 6.4 V. Dynamic single-mode operation of the laser was demonstrated numerically with a 200-Gbit/s non-return-to-zero (NRZ) modulation signal. A clear eye-opened optical NRZ pattern with a minimum extinction ratio at the eye-opening area of more than 1.0 dB was confirmed in a wide operation range and at a higher bit rate up to 300 Gbit/s.
期刊介绍:
The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
