Single- and Twin-Photons Emitted from Fiber-Coupled Quantum Dots in a Distributed Bragg Reflector Cavity

Abstract: In this work, we develop single-mode fiber devices of an InAs/GaAs quantum dot (QD) by bonding a fiber array with large smooth facet, small core, and small numerical aperture to QDs in a distributed Bragg reflector planar cavity with vertical light extraction that prove mode overlap and efficient output for plug-and-play stable use and extensive study. Modulated Si doping as electron reservoir builds electric field and level tunnel coupling to reduce fine-structure splitting (FSS) and populate dominant XX and … Show more

“…A QD micropillar array was used for this purpose, with the arrangement of the pillars chosen to match a fiber array consisting of 16 fibers that are usually used in a planar lightwave circuit splitter. In recent design optimizations, the authors increased efficiency while suppressing multiphoton states emission to a greater extent [158,159].…”
