Observation of Fundamental Charge Noise in Electro-Optic Photonics Integrated Circuits

Tobias Kippenberg, Johann Emmeram Riemensberger, Guanhao Huang, Zihan Li, Junyin Zhang

We observed a novel 1/f-type frequency noise in Lithium Niobate and Lithium Tantalate microresonators, distinct from thermorefractive noise and originating from thermodynamic charge fluctuations, setting the linewidth limits for integrated lasers. A charge ...

Continuous-wave electron-photon interactions using chip-based high-Q Si3N4 microresonator

Tobias Kippenberg, Junqiu Liu, Rui Ning Wang, Arslan Sajid Raja, Guanhao Huang

We observe CW-driven electron-photon interaction using a fiber-integrated high-Q Si3N4 microresonator, enabled by strong resonantly enhanced coupling with the confined optical mode. (C) 2021 The Author(s) ...

Reduced material loss in thin-film lithium niobate waveguides

Tobias Kippenberg, Guanhao Huang, Mikhail Churaev, Zihan Li

Thin-film lithium niobate has shown promise for scalable applications ranging from single-photon sources to high-bandwidth data communication systems. Realization of the next generation high-performance classical and quantum devices, however, requires much ...

Free Electron Interaction with Nonlinear Optical States

Tobias Kippenberg, Rui Ning Wang, Arslan Sajid Raja, Guanhao Huang, Zheru Qiu, Alexey Tikan, Aleksandr Tusnin, Yujia Yang

We couple free electrons with nonlinear optical states and frequency combs in photonic chip-based microresonators. Intracavity nonlinear dissipative structures including optical solitons imprint unique fingerprints in electron spectra and their Ramsey inte ...

Framework of Free-Electron Quantum Optics Using Photonic Integrated Circuits

Tobias Kippenberg, Guanhao Huang, Nils Johan Engelsen

We develop a framework of using photonic integrated circuits for free-electron quantum optics applications. We formulate the interaction using a three-dimensional QED quantization procedure, and discuss a few fundamental limitations and specific applicatio ...

Lithium-niobate-based narrow-linewidth frequency agile integrated lasers with petahertz frequency tuning rate

Tobias Kippenberg, Junqiu Liu, Rui Ning Wang, Johann Emmeram Riemensberger, Anat Siddharth, Guanhao Huang, Mikhail Churaev, Viacheslav Snigirev

We demonstrate an electro-optically tunable hybrid integrated laser self-injection locked to a mode of a heterogeneously integrated lithium-niobate-on-Damascene-silicon-nitride microresonator. An intrinsic linewidth of 3 kHz and a frequency tuning rate of ...

Room-temperature quantum optomechanics using an ultralow noise cavity

Tobias Kippenberg, Guanhao Huang, Nils Johan Engelsen, Alberto Beccari

At room temperature, mechanical motion driven by the quantum backaction of light has been observed only in pioneering experiments in which an optical restoring force controls the oscillator stiffness1,2. For solid-state mechanical resonators in which oscil ...

Probing the Material Loss and Optical Nonlinearity of Integrated Photonic Materials

Tobias Kippenberg, Junqiu Liu, Guanhao Huang

Optical absorption and nonlinear index are important performance drivers in devices like microcombs and parametric oscillators. Here we use resonance-enhanced nonlinear spectroscopy to characterize absorption limits and nonlinear index for some integrated ...

Probing the Limits of Optical Loss in Ion-Sliced Thin-film Lithium Niobate

Tobias Kippenberg, Junqiu Liu, Guanhao Huang, Mikhail Churaev, Zelin Tan

We measured the absorption-limited loss at telecommunication wavelengths for thin-film lithium niobate micro-ring resonators using Kerr-calibrated linear response technique. We find the average absorption loss-rate kappa(abs)/2 pi to be 3.65 +/- 0.70 MHz, ...

Lithium-Niobate-Based Frequency-Agile Integrated Lasers

Tobias Kippenberg, Junqiu Liu, Rui Ning Wang, Guanhao Huang, Anat Siddharth, Mikhail Churaev, Viacheslav Snigirev, Grigorii Likhachev

We demonstrate narrow- linewidth ultrafast tunable integrated lasers based on heterogeneously integrated thin-film lithium niobate on ultra-low loss silicon nitride integrated photonic circuits. Using self-injection locking of a hybrid microresonator, we a ...

Ultralow Dissipation Mechanical Resonators for Cavity-Free Quantum Control

Tobias Kippenberg, Guanhao Huang, Nils Johan Engelsen, Alberto Beccari, Amirali Arabmoheghi, Alessio Zicoschi

We fabricate nanomechanical resonators with Q > 109 at room temperature and show efficient optical readout of their motion. With an improved interferometer, these devices can be cooled close to the ground state without a cavity. ...
