Abstract
High-speed vertical-cavity surface-emitting lasers (VCSELs) with high single-mode (SM) output power and strong immunity to optical feedback play a vital role in further improving the package density in co-packaged optics (CPO) systems. Here, by optimizing the structure of VCSEL cavities with Zn-diffusion apertures inside, we can simultaneously improve the SM output power and speed of 850 nm VCSELs. With this novel structure we can achieve a record-high SM output power of 16 mW and a wide 3-dB electrical-to-optical (E-O) bandwidth of 18 GHz. Furthermore, excellent VCSEL performance can be obtained by varying the aperture size for high-speed operations, such as wide E-O bandwidth (27 GHz), high SM power (6.7 mW), low-RIN (−137 dB/Hz), and invariant 56 Gbps eye patterns under strong optical feedback (−6 dB). Error-free transmission can be achieved at around 48 Gbit/sec through 500 and 200 m multi-mode and single-mode fibers, respectively, without the use of equalizers in the transmission channels.
期刊介绍：
Papers published in the IEEE Journal of Selected Topics in Quantum Electronics fall within the broad field of science and technology of quantum electronics of a device, subsystem, or system-oriented nature. Each issue is devoted to a specific topic within this broad spectrum. Announcements of the topical areas planned for future issues, along with deadlines for receipt of manuscripts, are published in this Journal and in the IEEE Journal of Quantum Electronics. Generally, the scope of manuscripts appropriate to this Journal is the same as that for the IEEE Journal of Quantum Electronics. Manuscripts are published that report original theoretical and/or experimental research results that advance the scientific and technological base of quantum electronics devices, systems, or applications. The Journal is dedicated toward publishing research results that advance the state of the art or add to the understanding of the generation, amplification, modulation, detection, waveguiding, or propagation characteristics of coherent electromagnetic radiation having sub-millimeter and shorter wavelengths. In order to be suitable for publication in this Journal, the content of manuscripts concerned with subject-related research must have a potential impact on advancing the technological base of quantum electronic devices, systems, and/or applications. Potential authors of subject-related research have the responsibility of pointing out this potential impact. System-oriented manuscripts must be concerned with systems that perform a function previously unavailable or that outperform previously established systems that did not use quantum electronic components or concepts. Tutorial and review papers are by invitation only.
