A dual wavelength distributed-feedback fiber laser
A dual wavelength distributed-feedback fiber laser is a scholarly work, published in 2008 in ''Journal of Applied Physics''. The main subjects of the publication include laser, optical fiber, materials science, Mode volume, Lasing threshold, laser linewidth, optoelectronics, fiber laser, wavelength, fiber, Polarization-maintaining optical fiber, distributed feedback laser, frequency comb, optics, fiber-optic sensor, and photonic-crystal fiber. An approach to accessing air holes in a structured optical fiber with a distributed-feedback (DFB) laser based on higher order mode lasing is proposed and demonstrated.
