We report trace-gas absorption spectroscopy based on the efficient generation of a 3.05μm dispersive wave in a Si3N4 waveguide pumped by a 2.09 μm femtosecond mode-locked fiber laser ...

Thermodynamic noises limit the frequency stability of resonators. Here, we present the first complete characterization of thermo-refractive noise in Si3N4 microresonators. The measurements are in good agreement with theoretical analysis and FEM simulation ...

The ability to amplify optical signals is of pivotal importance across science and technology typically using rare-earth-doped fibres or gain media based on III-V semiconductors. A different physical process to amplify optical signals is to use the Kerr no ...

Dissipative Kerr solitons have recently been generated in optical microresonators, enabling ultrashort optical pulses at microwave repetition rates, that constitute coherent and numerically predictable Kerr frequency combs. However, the seeding and excitat ...

This research tests the potential susceptibility of a prevalent, residential, wall assembly to the risk of sustained mold-growth in predicted future climate conditions. Here, the authors demonstrate a methodology that combines hygrothermal and mold-growth ...

Recent developments in chip-based nonlinear photonics offer the tantalizing prospect of realizing many applications that can use optical frequency comb devices that have form factors smaller than 1 cm(3) and that require less than 1 W of power. A key featu ...

The theory of quantum measurement of mechanical motion, describing the mutual coupling of a meter and a measured object, predicts a variety of phenomena such as quantum backaction, quantum correlations and non-classical states of motion. In spite of great ...

We experimentally demonstrate optical multicasting using Kerr frequency combs generated from a Si3N4 microresonator. We obtain Kerr combs in two states with different noise properties by varying the pump wavelength in the resonator and investigate the effe ...

We demonstrate a current-initiated soliton microcomb by injection-locking a multi-frequency laser diode to a chip-scale high-Q Si3N4 microresonator. This approach offers a pathway for integrated and ultra-compact microcomb source for high-volume applicatio ...

On-chip Kerr frequency combs are potentially promising to enhance many applications because of their broad-band operation and chip-scale integration. Such combs offer various mutually coherent optical carriers that can potentially be used as both coherent ...

On-chip coherent light generation has wide-ranging applications in metrology, spectroscopy, quantum optics, etc. In this study, we demonstrate the generation of coherent light from a silicon-nitride microring resonator using cascaded nonlinear processes. T ...

A photonic dimer composed of two evanescently coupled high-Q microresonators is a fundamental element of multimode soliton lattices. It has demonstrated a variety of emergent nonlinear phenomena, including supermode soliton generation and soliton hopping. ...

The inherent coupling of optical and mechanical modes in high finesse optical microresonators provides a natural, highly sensitive transduction mechanism for micromechanical vibration. Using homodyne and polarization spectroscopy techniques, we achieve sho ...

The experimental study of the InPlaser diode stabilization by high-Q Si3N4 microresonator is presented. We demonstrate how this stabilized laser diode considered as a pump laser may be used for optical frequency comb generation in the same microresonator. ...

Using the photonic Damascene reflow process, we present single soliton formation in 99-GHz-FSR Si3N4 microresonators of Q-factor exceeding 15 x 10(6), with less than 10 mW optical power. ...

Vacuum-gap capacitors have recently attracted significant interest in superconducting circuit platforms due to their compact design and exceptionally low dielectric losses in the microwave regime. Their intrinsic ability to support mechanical vibrational m ...

Quasi-phase-matching (QPM) has become one of the most common approaches for increasing the efficiency of nonlinear three-wave mixing processes in integrated photonic circuits. Here, we provide a study of dispersion engineering of QPM second-harmonic (SH) g ...

We demonstrate a novel technique of contour-mode suppression of an integrated MEMS-photonic chip up to the first HBAR mode at 17 MHz. The flattened actuation response is critical to the development of compact LiDAR engine or low-noise frequency-agile laser ...

The continuous growth of global data traffic over the past three decades, along with advances in disaggregated computing architectures, presents significant challenges for optical transceivers in communication networks and high-performance computing system ...

Although invented for precision measurements of single atomic transitions, frequency combs have also become a versatile tool for broadband spectroscopy in recent years. Here, we present a novel and simple approach for broadband spectroscopy, combining the ...
