Mode-Locking Method Shows Stable Output, Potential for Tiny Lasers
An international team of researchers used a microcavity ring resonator as both a laser filter and mode-locker.
A monolithically integrated 4-port microring resonator acts as both a filter within the laser cavity and as a nonlinear gain medium within the erbium-doped fiber-based laser. The waveguide is made of high index doped silica glass.
An international team of researchers used a microcavity ring resonator as both a laser filter and mode-locker. The laser emits pulses of light with unusually stable operation at repetition rates as high as 200 GHz while maintaining very narrow linewidths below 130 kHz (Nat. Commun., DOI: 10.1038/ncomms1762).
