A Novel Widely Continuously Tunable Laser Using A Couple of Vernier Caliper Gratings

摘要

A novel widely tunable fiber laser which can rapidly select the desired ITU-T wavelength has been proposed. This multiwavelength source, based on vernier caliper component(two sampled fiber Bragg gratings with a slight different in channel separation) appears very promising for wavelength division multiplexing since which has many advantages such as a widely tuning range of selective wavelength, easily lock to the wavelength separation, cheap costly, stable performance and so on.
