When AI And Optoelectronics Meet: Researchers Take Control Of Light Properties

Researchers can now customize the properties of broadband light sources using machine learning and an integrated photonic chip.

They successfully produced and manipulated intense ultrashort pulse patterns, which are used to generate a broadband optical spectrum. Recently, the development of laser sources with intense and ultrashort laser pulses and methods to spatially confine and guide light propagation has given rise to enormously powerful optical architectures. With these new systems, a slew of new possibilities emerges, including the generation of supercontinua or extended light spectra produced by intense light-matter interactions.

Such powerful and complex optical systems and their associated processes are now the foundation for many applications, from laser science and metrology to advanced sensing and biomedical imaging techniques. More tailoring capability of light properties is required to continue pushing the limits of these technologies. The team’s work reveals a practical and scalable solution to this problem.

They used integrated photonic structures’ compactness, stability, and sub-nanometer resolution to generate reconfigurable bunches of ultrashort optical pulses. Researchers demonstrated that controlling and customizing the output light is efficient when using their system and a suitable algorithm to explore the vast array of available light pulse patterns.

The team’s work is expected to pave the way for developing other smart optical systems using self-optimization techniques.
