We demonstrate a photonic integrated circuit-based Erbium laser by endowing an ultralow-loss silicon nitride integrated optical cavity with Erbium-based gain. The free-running laser achieves 50 Hz intrinsic linewidth, 17 mW output power, and 40 nm waveleng ...

We demonstrate a hydrogen-free low-loss silicon oxide film deposited with SiCl4 and O2 precursor. A very wide low-loss window of 1300 nm to 1620 nm is achieved at deposition temperature as low as 300 ◦C. ...

We demonstrate a photonic-electronic analog-to-digital converter (ADC) offering a record-high acquisition bandwidth of 320 GHz. The system combines a high-speed electro-optic modulator with a Kerr comb for spectrally sliced coherent detection and is used f ...

We experimentally discovered and theoretically explain a novel turnkey regime for operation of soliton microcombs, wherein a new operating point enables the direct access of the soliton state by simple turn-on of the pump laser. (C) 2020 The Author(s) ...

We report the first demonstration of microresonator dark pulse generation by self-injection locking of a DFB laser to a Si3N4 microresonator with normal GVD. The 26 GHz repetition rate beatnote is characterized. (C) 2020 The Author(s) ...

Stable and tunable integrated lasers are fundamental building blocks for applications from spectroscopy to imaging and communication. Here the authors present a narrow linewidth hybrid photonic integrated laser with low frequency noise and fast linear wave ...

We demonstrate a traveling wave parametric amplifier in a photonic Si3N4 integrated spiral waveguide of 2.0 m length with footprint 3x5 mm. We achieve net gain of 7 dB on-chip and 2 dB fiberto-fiber in the optical C-band. (C) 2022 The Author(s) ...

We implement Euler bends to build compact high-Q Si3N4 racetrack microresonators, featuring a small footprint of only 0.21 mm(2) for 19.8 GHz FSR. We demonstrate that these multi-mode microresonators can be operated in the single-mode regime and generate a ...
