Linear and nonlinear applications of miniaturized silicon nitride microresonators
Photonic integrated circuits (PICs) are the subject of massive interest due to the range of applications they can provide at a huge scale while building on well-established CMOS technologies. One of the critical parameters defining a technology's maturity ...
EPFL2023Sub-kHz-Linewidth External-Cavity Laser (ECL) With Si3N4 Resonator Used as a Tunable Pump for a Kerr Frequency Comb
Combining optical gain in direct-bandgap III-V materials with tunable optical feedback offered by advanced photonic integrated circuits is key to chip-scale external-cavity lasers (ECL), offering wideband tunability along with low optical linewidths. Exter ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2023Spatiotemporal dissipative soliton resonances in multimode fiber lasers
Haoye Qin, Gang Wang, Bo Fu, Xuchen Wang, Hao Ouyang
Spatiotemporal mode-locking in multimode fiber lasers is intriguing for the complex nonlinear dynamics and the increase of theoretical energy limit. In this paper, we enrich spatiotemporal mode-locking with dissipative soliton resonances, a kind of soliton ...
PERGAMON-ELSEVIER SCIENCE LTD2023Hybrid lithium niobate-on-silicon nitride platform for mid-IR supercontinuum generation
Tobias Kippenberg, Mikhail Churaev
Integrated optics has shown itself very convenient for exploiting nonlinear processes as it results in high confinement factor, freedom of dispersion engineering and compactness. However, the choice of materials is crucial for the development of nonlinear ...
SPIE-INT SOC OPTICAL ENGINEERING2023Ultra low quantum decoherence nano-optomechanical systems
Thermal motion of a room-temperature mechanical resonator typically dominates the quantum backaction of its position measurement. This is a longstanding barrier for exploring cavity optomechanics at room temperature. In order to enter the quantum regime of ...
EPFL2022Exploring nonlinearities in multimode optical fibers for lasers and computing
Multimode optical fibers are the backbone of telecommunication and medical imaging. When light with high intensity travels through a multimode fiber, photons and matter start to interact and propa-gation becomes nonlinear. The nonlinear propagation of ligh ...
EPFL2021Highly efficient THz four-wave mixing in doped silicon
Third-order non-linearities are important because they allow control over light pulses in ubiquitous high-quality centro-symmetric materials like silicon and silica. Degenerate four-wave mixing provides a direct measure of the third-order non-linear sheet ...

Tobias Kippenberg, Hairun Guo, Arslan Sajid Raja
A light pulse source (100), being adapted for generating repetitive optical pulses (1), comprises a continuous wave cw laser device (10) being arranged for providing cw laser light (2), an optical waveguide (20) being optically coupled with the cw laser de ...
2020Fiber-interface directional coupler inscribed by femtosecond laser for refractive index measurements
Jiangtao Zhou, Zhechen Zhang, Yiping Wang, Jiachen Wang
A novel fiber-interface directional waveguide coupler was inscribed on the surface of a coreless fiber by femtosecond laser, and was successfully applied to highly sensitive refractive index (RI) measurements. The primary arm was first inscribed to couple ...
