Journal ArticleDOI
Diamond nonlinear photonics
Birgit Hausmann,Irfan Bulu,Irfan Bulu,Vivek Venkataraman,Parag B. Deotare,Parag B. Deotare,Marko Loncar +6 more
TL;DR: In this article, an optical parametric oscillator in the telecom wavelength range is realized in a diamond system consisting of a ring resonator coupled to a diamond waveguide, and threshold powers as low as 20mW are measured and up to 20 new wavelengths are generated from a single-frequency pump laser.
Journal ArticleDOI
Integrated high quality factor lithium niobate microdisk resonators.
Cheng Wang,Michael J. Burek,Zin Lin,Haig A. Atikian,Vivek Venkataraman,I-Chun Huang,Peter R. H. Stark,Marko Loncar +7 more
TL;DR: Lithium Niobate microdisk resonators that feature optical quality factor ~10(5) are demonstrated using robust and scalable fabrication techniques, that operate over a wide wavelength range spanning visible and near infrared.
Journal ArticleDOI
Phase modulation at the few-photon level for weak-nonlinearity-based quantum computing
TL;DR: In this article, the authors demonstrate large cross-phase shifts of 0.3 mrad per photon in a single pass through room-temperature Rb atoms confined to a hollow-core photonic bandgap fiber.
Journal ArticleDOI
Second harmonic generation in nano-structured thin-film lithium niobate waveguides.
Cheng Wang,Xiao Xiong,Nicolas M. Andrade,Vivek Venkataraman,Xi-Feng Ren,Guang-Can Guo,Marko Loncar +6 more
TL;DR: In this article, phase-matched second harmonic generation in thin-film lithium niobate waveguides with sub-micron dimensions has been demonstrated and experimentally demonstrated with low-loss (~3.0 dB/cm) nanowaveguides.
