Here, we present InAs/GaAs quantum dots microdisk lasers monolithically grown on on-axis Si (001) substrate with ultra-low lasing threshold under room-temperature continues-wave optical pumping. The promising lasing characteristics of the microdisk lasers with ultra-low threshold and small footprint represent a major advance towards large-scale, low-cost integration of laser sources on silicon-based platform. date: 2019-01-01 date_type: published publisher: SPIE official_url: http://dx.doi.org/10.1117/12.2538773 oa_status: green full_text_type: pub language: eng primo: open primo_central: open_green verified: verified_manual elements_id: 1747002 doi: 10.1117/12.2538773 isbn_13: 9781510630819 lyricists_name: Chen, Siming lyricists_name: Liu, Huiyun lyricists_name: Tang, Mingchu lyricists_name: Zhou, Taojie lyricists_id: SCHEA37 lyricists_id: HLIUX22 lyricists_id: TANGX88 lyricists_id: TZHOA30 actors_name: Dewerpe, Marie actors_id: MDDEW97 actors_role: owner full_text_status: public publication: Proceedings of SPIE - The International Society for Optical Engineering volume: 11182 place_of_pub: Hangzhou, China pagerange: 1118208 event_title: SPIE/COS Photonics Asia issn: 1996-756X book_title: Proceedings of SPIE 11182, Semiconductor Lasers and Applications IX citation: Zhou, T; Tang, M; Xiang, G; Chen, S; Liu, H; Zhang, Z; (2019) Optically-pumped InAs/GaAs quantum-dot microdisk lasers monolithically grown on on-axis Si (001) substrate.
