Stimulated Brillouin scattering (SBS) is a nonlinear optical phenomenon mediated from the coupling of photons and phonons. It has found applications in various realms, yet the acousto-optic interaction strength remains relatively weak. Enhancing the SBS with resonant structures could be a promising solution, but this method faces strict constraints in operational bandwidth.

Advancements in photonic integration technology have enabled the effective excitation of simulated Brillouin scattering (SBS) on a single chip, boosting Brillouin-based applications such as microwave photonic signal processing, narrow-linewidth lasers, and optical sensing. However, on-chip circuits still require large pump power and centimeter-scale waveguide length to achieve a considerable Brillouin gain, making them both power-inefficient and challenging for integration.

In this series, we have explored whether IP rights protect AI systems themselves and whether copyright or patents provide protection for AI-generated works or inventions, however, equally as controversial is the way in which AI systems use others’ works. At their core AI systems are computer systems, working on large volumes of data. Those systems – and most obviously those data – are often the products of others’ intellectual and economic investment.

The acousto-optic interaction known as stimulated Brillouin scattering (SBS) has emerged as a fundamental principle for realizing crucial components and functionalities in integrated photonics. However, the main challenge of integrating Brillouin devices is how to effectively confine both optical and acoustic waves. Apart from that, the manufacturing processes for these devices need to be compatible with standard fabrication platforms and streamlined to facilitate their large-scale integration.

In 2024, a significant milestone was achieved with the implementation of the “Regulation on the Implementation of the Law on the Protection of Consumer Rights and Interests” by the Chinese State Council. This is the first administrative regulation supporting the “PRC Consumer Rights Protection Law” since its enactment in 1993.
