Electrically Driven Ultra-compact Photonic Integrated Soliton Microcomb

Tobias Kippenberg, Junqiu Liu, Maxim Karpov, Hairun Guo, Erwan Guillaume Albert Lucas, Arslan Sajid Raja, John David Jost, Andrey Voloshin

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 ...

Passivity-based Voltage and Frequency Stabilization in AC microgrids

Giancarlo Ferrari Trecate, Pulkit Nahata

In this paper, we investigate the stability of an islanded AC microgrid (ImG) composed of Distributed generation units (DGUs), dynamic power lines, and loads. Each DGU is equipped with a local controller to ensure desired voltage and frequency in the ImG. ...

Spectral Purification of Microwave Signals with Disciplined Dissipative Kerr Solitons

Tobias Kippenberg, Hairun Guo, Erwan Guillaume Albert Lucas, Wenle Weng

Continuous-wave-driven Kerr nonlinear microresonators give rise to self-organization in terms of dissipative Kerr solitons, which constitute optical frequency combs that can be used to generate low-noise microwave signals. Here, by applying either amplitud ...

Comprehensive Analysis and Design of a Quasi Two-Level Converter Leg

Drazen Dujic, Stefan Milovanovic

Quasi two-level operation of voltage source converters, intended to operate either within high/medium voltage DC networks or low output frequency applications, has caught the attention of both academia and industry. Sequential insertion of the so-called su ...

Coherent Dynamics of Nanowire Force Sensors

Anna Fontcuberta i Morral, Gözde Tütüncüoglu

We describe the use of grown nanowires as scanning directional force sensors. Two orthogonal flexural modes are used to demonstrate vectorial sensing of electric and magnetic fields. Furthermore, we show that the modes can be strongly coupled by demonstrat ...

Mutually Coupled Time-to-Digital Converters (TDCs) for Direct Time-of-Flight (dTOF) Image Sensors

Edoardo Charbon, Preethi Padmanabhan, Augusto Ronchini Ximenes

Direct time-of-flight (dTOF) image sensors require accurate and robust timing references for precise depth calculation. On-chip timing references are well-known and understood, but for imaging systems where several thousands of pixels require seamless refe ...
