Abstract

A planar In0.53Ga0.47As avalanche photodiode (APD) with a triple-stage cascaded InAlAs/InAlGaAs multiplication structure is designed and fabricated. Double zinc-diffusion p-n junction is formed to suppress the perimeter premature breakdown. A low dark current of 4.8 nA at around breakdown voltage is obtained at room temperature for a

$40~\mu $

m diameter device with a maximum gain-bandwidth product of 216 GHz. The E-field profile is modulated by doping of a thin In0.52Al0.48As subcharge layer within each multiplication stage. Moreover, electron and hole potential wells are also introduced by the In0.52Al0.24Ga0.24As layers within each stage. The measured hole-initiated maximum gain factor and excess noise factor are 77 and F=6.3 at 200 K, respectively, which well agree with the predicted results base on the dead-space multiplication theory. These results indicate the planar multi-stage multiplication regime is a viable route for fabrication of APDs towards low excess noise while maintaining of a low dark current.

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.
