High-pulse-energy integrated mode-locked laser using a Mamyshev oscillator (opens in new tab)

Ultrafast lasers have led to numerous advances across science and technology: they enabled corneal surgery1, revealed chemical reaction dynamics2 and triggered the development of optical atomic clocks3. Over the past decades, extensive efforts have aimed to realize mode-locked lasers based on photonic integrated circuits (PICs) that are compact, manufactured at wafer scale and are compatible with further on-chip functionalities4–6. Yet, existing demonstrations to date lack the pulse energy re...
