Journal ArticleDOI
Electronic structure of the silicon vacancy color center in diamond
Christian Hepp,Tina Müller,Victor Waselowski,Jonas Nils Becker,Benjamin Pingault,H. Sternschulte,Doris Steinmüller-Nethl,Adam Gali,Adam Gali,Jeronimo R. Maze,Mete Atatüre,Christoph Becher +11 more
TL;DR: The similar responses of single centers and a SiV ensemble in a low strain reference sample prove the ability to fabricate almost perfect single SiVs, revealing the true nature of the defect's electronic properties.
Journal ArticleDOI
One- and two-dimensional photonic crystal microcavities in single crystal diamond
Janine Riedrich-Möller,Laura Kipfstuhl,Christian Hepp,Elke Neu,Christoph Pauly,Frank Mücklich,Armin Baur,Michael Wandt,Sandra Wolff,Martin Fischer,Stefan Gsell,Matthias Schreck,Christoph Becher +12 more
TL;DR: This work presents a method for the fabrication of one- and two-dimensional photonic crystal microcavities with quality factors of up to 700 in single crystal diamond using a post-processing etching technique.
Journal ArticleDOI
Visible-to-telecom quantum frequency conversion of light from a single quantum emitter.
Sebastian Zaske,Andreas Lenhard,Christian A. Kesler,Jan Kettler,Christian Hepp,Carsten Arend,Roland Albrecht,Wolfgang-Michael Schulz,Michael Jetter,Peter Michler,Christoph Becher +10 more
TL;DR: Analysis of the first- and second-order coherence before and after wavelength conversion clearly proves that pivotal properties, such as the coherence time and photon antibunching, are fully conserved during the frequency translation process.
Journal ArticleDOI
Optical signatures of silicon-vacancy spins in diamond
Tina Müller,Christian Hepp,Benjamin Pingault,Elke Neu,Stefan Gsell,Matthias Schreck,H. Sternschulte,Doris Steinmüller-Nethl,Christoph Becher,Mete Atatüre +9 more
TL;DR: Measurements reveal a spin-state purity approaching unity in the excited state, highlighting the potential of the silicon-vacancy centre as an efficient spin-photon quantum interface.
Journal ArticleDOI
Low-temperature investigations of single silicon vacancy colour centres in diamond
Elke Neu,Elke Neu,Christian Hepp,Michael Hauschild,Stefan Gsell,Martin Fischer,H. Sternschulte,Doris Steinmüller-Nethl,Matthias Schreck,Christoph Becher +9 more
TL;DR: In this paper, the authors investigated the temperature-dependent fine structure of the zero-phonon line (ZPL) of the SiV centres in chemical vapour deposition (CVD) nanodiamonds on iridium and an ensemble of SiV centers in a high-quality, low-stress CVD diamond film.
