While poised to impact major photonic applications, such as spectroscopy, sensing and optical data processing, microcombs still necessitate complex scientific equipment to achieve and maintain suitable single-pulse operation. Here, to address this challenge, we demonstrate microresonators with programmable synthetic reflection providing an injection-feedback to the driving laser. When designed appropriately, the synthetic reflection enables robust access to self-injection-locked microcombs operating exclusively in the single-soliton regime and with low-threshold power. These results provide a route to easily-operable microcombs for portable sensors, autonomous navigation, or extreme-bandwidth data processing and represent a novel paradigm that can be generalized to other integrated photonic systems. 000517461 536__ $$0G:(DE-HGF)POF4-631$$a631 - Matter – Dynamics, Mechanisms and Control (POF4-631)$$cPOF4-631$$fPOF IV$$x0 000517461 536__ $$0G:(EU-Grant)853564$$aSTARCHIP - Microphotonics-based frequency combs for habitable exoplanet detection (853564)$$c853564$$fERC-2019-STG$$x1 000517461 536__ $$0G:(EU-Grant)965124$$aFEMTOCHIP - FEMTOSECOND LASER ON A CHIP (965124)$$c965124$$fH2020-FETOPEN-2018-2019-2020-01$$x2 000517461 536__ $$0G:(DE-HGF)2019_VH-NG-1404$$aVH-NG-1404 - Ultra-fast nonlinear microphotonics (G:(DE-HGF)2019_VH-NG-1404)$$cG:(DE-HGF)2019_VH-NG-1404$$x3 000517461 693__ $$0EXP:(DE-H253)CFEL-Exp-20150101$$5EXP:(DE-H253)CFEL-Exp-20150101$$eExperiments at CFEL$$x0 000517461 7001_ $$0P:(DE-H253)PIP1094154$$aWildi, Thibault$$b1 000517461 7001_ $$0P:(DE-HGF)0$$aPavlov, Nikolay G.$$b2 000517461 7001_ $$0P:(DE-HGF)0$$aJost, John D.$$b3 000517461 7001_ $$0P:(DE-HGF)0$$aKarpov, Maxim$$b4 000517461 7001_ $$0P:(DE-H253)PIP1092814$$aHerr, Tobias$$b5$$eCorresponding author 000517461 773__ $$a10.48550/arXiv.2301.13132$$tarXiv$$y2023 000517461 8564_ $$uhttps://arxiv.org/abs/2301.13132 000517461 8564_ $$uhttps://bib-pubdb1.desy.de/record/517461/files/HTML-Approval_of_scientific_publication.html 000517461 8564_ $$uhttps://bib-pubdb1.desy.de/record/517461/files/PDF-Approval_of_scientific_publication.pdf 000517461 8564_ $$uhttps://bib-pubdb1.desy.de/record/517461/files/internal_review.pdf 000517461 8564_ $$uhttps://bib-pubdb1.desy.de/record/517461/files/2301.13132v1.pdf$$yOpenAccess 000517461 8564_ $$uhttps://bib-pubdb1.desy.de/record/517461/files/internal_review.pdf?subformat=pdfa$$xpdfa 000517461 8564_ $$uhttps://bib-pubdb1.desy.de/record/517461/files/2301.13132v1.pdf?subformat=pdfa$$xpdfa$$yOpenAccess 000517461 909CO $$ooai:bib-pubdb1.desy.de:517461$$pdnbdelivery$$pec_fundedresources$$pVDB$$pdriver$$popen_access$$popenaire 000517461 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1101456$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000517461 9101_ $$0I:(DE-H253)_CFEL-20120731$$6P:(DE-H253)PIP1101456$$aCentre for Free-Electron Laser Science$$b0$$kCFEL 000517461 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1094154$$aDeutsches Elektronen-Synchrotron$$b1$$kDESY 000517461 9101_ $$0I:(DE-H253)_CFEL-20120731$$6P:(DE-H253)PIP1094154$$aCentre for Free-Electron Laser Science$$b1$$kCFEL 000517461 9101_ $$0I:(DE-HGF)0$$6P:(DE-HGF)0$$aEnlightra Sarl, Rue de Lausanne 64, 1020 Renens, Switzerland$$b2 000517461 9101_ $$0I:(DE-HGF)0$$6P:(DE-HGF)0$$aEnlightra Sarl, Rue de Lausanne 64, 1020 Renens, Switzerland$$b3 000517461 9101_ $$0I:(DE-HGF)0$$6P:(DE-HGF)0$$aEnlightra Sarl, Rue de Lausanne 64, 1020 Renens, Switzerland$$b4 000517461 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1092814$$aDeutsches Elektronen-Synchrotron$$b5$$kDESY 000517461 9101_ $$0I:(DE-H253)_CFEL-20120731$$6P:(DE-H253)PIP1092814$$aCentre for Free-Electron Laser Science$$b5$$kCFEL 000517461 9131_ $$0G:(DE-HGF)POF4-631$$1G:(DE-HGF)POF4-630$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lFrom Matter to Materials and Life$$vMatter – Dynamics, Mechanisms and Control$$x0 000517461 9141_ $$y2023 000517461 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000517461 915__ $$0LIC:(DE-HGF)CCBYNCSA4$$2HGFVOC$$aCreative Commons Attribution-NonCommercial-ShareAlike CC BY-NC-SA 4.0 000517461 915__ $$0StatID:(DE-HGF)0580$$2StatID$$aPublished 000517461 9201_ $$0I:(DE-H253)FS-CFEL-2-UMP-20201209$$kFS-CFEL-2-UMP$$lFS-CFEL-2-UMP$$x0 000517461 980__ $$apreprint 000517461 980__ $$aVDB 000517461 980__ $$aUNRESTRICTED 000517461 980__ $$aI:(DE-H253)FS-CFEL-2-UMP-20201209 000517461 9801_ $$aFullTexts
