    Progress in Passively Mode-Locked Laser Technology for Ring Cavities at Suzhou Institute of Nano-Tech

    A team at the Suzhou Institute of Nano-Tech and Nano-Bionics, Chinese Academy of Sciences, has developed a theoretical model for PML-SRLs, revealing that operating states are governed by the temporal balance of gain and loss. Combining time-domain traveling-wave equations with partial differential equations for carrier density, the model examines the relationship between SOA carrier accumulation rate, SA carrier lifetime and ring cavity round-trip time. The work, published in Optics Express, also found that an SOA with a narrow gain spectrum and a short resonator configuration can merge output pulses to produce high-energy optical pulses.

    Why we recommend it: Putting gain, absorber and cavity round-trip time into a unified dynamic model offers transferable design insight into mode-locking states and pulse merging in semiconductor ring cavities.
