Reinforcement learning accelerates laser design, Dueling DQN shows promise

Researchers have developed a new method using value-based reinforcement learning to accelerate the design of photonic-crystal surface-emitting lasers (PCSELs). In a study with a limited simulation budget of 83 calls, Dueling DQN demonstrated the most reliable performance, improving key metrics such as quality factor, wavelength error, and upward power compared to baseline DQN and other variants. This approach offers a reproducible framework for attributing algorithmic gains in scientific optimization, with the source code made publicly available. AI

IMPACT This research demonstrates a more efficient method for optimizing complex scientific designs, potentially reducing computational costs and accelerating discovery in fields like photonics.
