High-yield, wafer-scale fabrication of ultralow-loss, dispersion-engineered silicon nitride photonic circuits

Tobias Kippenberg, Rui Ning Wang, Guanhao Huang, Junqiu Liu, Arslan Sajid Raja, Jijun He, Nils Johan Engelsen, Tianyi Liu

Low-loss photonic integrated circuits and microresonators have enabled a wide range of applications, such as narrow-linewidth lasers and chip-scale frequency combs. To translate these into a widespread technology, attaining ultralow optical losses with est ...

Probing the Material Loss and Optical Nonlinearity of Integrated Photonic Materials

Tobias Kippenberg, Guanhao Huang, Junqiu Liu

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 ...

Smooth GaN membranes by polarization-assisted electrochemical etching

Nicolas Grandjean, Jean-François Carlin, Joachim Armand Simonne Ciers

III-nitride membranes offer promising perspectives and improved device designs in photonics, electronics, and optomechanics. However, the removal of the growth substrate often leads to a rough membrane surface, which increases scattering losses in optical ...

Emergent nonlinear phenomena in a driven dissipative photonic dimer

Tobias Kippenberg, Rui Ning Wang, Mikhail Churaev, Kenichi Komagata, Junqiu Liu, Hairun Guo, Alexey Tikan

Collective effects leading to spatial, temporal or spatiotemporal pattern formation in complex nonlinear systems driven out of equilibrium cannot be described at the single-particle level and are therefore often called emergent phenomena. They are characte ...

Advanced Progress on chi((3)) Nonlinearity in Chip-Scale Photonic Platforms

Jijun He, Qian Li, Feng Li

chi((3)) nonlinearity enables ultrafast femtosecond scale light-to-light coupling and manipulation of intensity, phase, and frequency. chi((3)) nonlinear functionality in micro- and nanoscale photonic waveguides can potentially replace bulky fiber platform ...

Advanced methods for Brillouin based distributed optical fiber sensors

Simon Adrien Zaslawski

After more than thirty years of continuous research and development, the performances of conventional Brillouin based distributed optical fiber sensors (DOFS) are now peaking, as they are facing fundamental barriers that restrict the power of the light inj ...

A cryogenic electro-optic interconnect for superconducting devices

Tobias Kippenberg, Amir Youssefi, Anton Lukashchuk, Nathan Rafaël Bernier, Liu Qiu, Itay Shomroni

A major challenge to the scalability of cryogenic computing platforms is the heat load associated with the growing number of electrical cable connections between the superconducting circuitry and the room-temperature environment. Compared with electrical c ...

Nanophotonic structures with optical surface modes for tunable spin current generation

Pavel Kapralov

We propose a novel type of photonic-crystal (PC)-based nanostructures for efficient and tunable optically-induced spin current generation via the spin Seebeck and inverse spin Hall effects. It has been experimentally demonstrated that optical surface modes ...

Nonlinear Frequency Conversion in the Hybrid Silicon Nitride - Lithium Niobate Integrated Platform

Tobias Kippenberg, Rui Ning Wang, Mikhail Churaev, Viacheslav Snigirev, Junqiu Liu

We demonstrate optical frequency comb generation in hybrid high-Q optical microresonators fabricated using direct wafer bonding of photonic Damascene silicon nitride wafer with thin-film lithium niobate-on-insulator (LNOI). The devices enable direct phase ...
