Self -locking microquoms scattered on a chip teams to achieve a wide spectrum and stable output

A research team has successfully developed a lithium nebatic chip itself, developed by Raman Electro Optic (ReO) microcoomb. With a microzonator, an electro -optic (EO), a combination of Kerr and Raman effects, is more than 300 nm, a versum width of microcomb is more than 300 nm and repetition rate of 26.03 GHz, without the need for outdoor electronic feedback.

It was published in research Nature communications. The team was led by Professor Dong Chinhwa from the University of Science and Technology of China (USTC) in partnership with Professor Bo Fung’s group from Nanaki University.

Optical frequency kings, light sources of lighting are the same as frequency lines, modern optical communication, precision measurement, and basic physics research are essential tools. Although traditional optical frequency kings are usually based on heavy laser lasers, recent developments in integrated photonics have enabled chip Scale Care and EO Cumbus.

However, these integrated solutions still face challenges in achieving a wide variety of output and low noise stability. Specifically, Raman scattered, such as parasitic non -liner effects, which are often found on high pump powers, can limit the performance of microorganisms.

In this work, researchers suggested and demonstrated a novel mechanism to create a self -locking broadband Reo Microquay. They turned Raman into a beneficial non -liner process. The new mechanism to create a number of EO Kings’ sets of EO Kings took advantage of Raman scattered and EO Modelon, while four views (FWM) expanded the spectrum. Critically, the combination lines starting with Raman laser are automatically locked by the primary pump light on the comb lines, ensuring high harmony throughout the system without external intervention.

As a result, the broadband REO microcoomb, which is produced in the same lithium neonabate restrick microzonator, spreads more than 300 nm, which includes more than 1400 individual comb lines at the repetition rate of 26.03 GHz. The system automatically showed high harmony and high -speed tonnes, while automatically acquired the phase pond. In addition, the repetition rate of the microcomb has exhibited a self -locking tuning range of about 550 kg, which can be extended to 8 MW through thermal tining through microwave power adjustment.

This work sets an experimental platform to find complex multi -nun liner physical processes, such as injection locking and self -harmony. With its wide bandoth and strong self -pond, the Reo Microorbes promise to high resolution spectroscopy, advanced optical communication, and quantum information processing applications.
