Self-injection-locked optical parametric oscillator based on microcombs
Fuchuan Lei, Yi Sun, Óskar B. Helgason +5
Narrow-linewidth yet tunable laser oscillators are one of the most important tools for precision metrology, optical atomic clocks, sensing and quantum computing. Commonly used tuna…
Integrated, ultra-compact high-Q silicon nitride microresonators for low-repetition-rate soliton microcombs
Zhichao Ye, Fuchuan Lei, Krishna Twayana +3
Multiple applications of relevance in photonics, such as spectrally efficient coherent communications, microwave synthesis or the calibration of astronomical spectrographs, would b…
Overcoming the quantum limit of optical amplification in monolithic waveguides
Zhichao Ye, Ping Zhao, Krishna Twayana +3
Optical amplifiers are essential in numerous photonic applications. Parametric amplifiers, relying on a nonlinear material to create amplification, are uniquely promising as they c…
Power Efficient Communication for Low Signal to Noise Ratio Optical Links
Ravikiran Kakarla, Mikael Mazur, Jochen Schröder +1
Receiver sensitivity is a particularly important metric in optical communication links operating at low signal-to-noise ratios (SNRs), for example in deep-space communication, sinc…
Widely Tunable, Low Linewidth, and High Power Laser Source using an Electro-Optic Comb and Injection-Locked Slave Laser Array
J Connor Skehan, Corentin Naveau, Jochen Schroder +1
We propose a simple approach to implement a tunable, high power and narrow linewidth laser source based on a series of highly coherent tones from an electro-optic frequency comb an…
Dissipative Kerr solitons in photonic molecules
Óskar B. Helgason, Francisco R. Arteaga-Sierra, Zhichao Ye +5
Many physical systems display quantized energy states. In optics, interacting resonant cavities show a transmission spectrum with split eigenfrequencies, similar to the split energ…
