MODE-LOCKED FABRY-PEROT LASER DEVICE PROVIDED WITH MULTI-RESONATOR AND WAVELENGTH DIVISION MULTIPLEXING LIGHT SOURCE USING THE SAME

摘要

PURPOSE: A mode-locked Fabry-Perot laser device provided with a multi-resonator and wavelength division multiplexing light source using the same are provided to make the oscillation modes dense by providing with a first and a second resonators. CONSTITUTION: A mode-locked Fabry-Perot laser device(200) provided with a multi-resonator includes a Fabry-Perot layer(210) provided with a first reflector(212) and a second reflector(214) and a reflective material(234) as a third reflector. The third reflector at the outside of the Fabry-Perot laser(210) and forms a second resonator together with the first resonator.
