A cost-effective wavelength selectable light source comprising a distributed feedback (DFB) fibre laser array is proposed. A large number of wavelengths can be selected via optical space switches using only one shared pump laser. The structure is a good candidate for use as a wavelength selectable...
Based on a DFB grating design we have developed a four wavelength laser array with excellent single mode operation and high power output. We could routinely stabilize a high level of single laser yield of about 90% and hence, array yields better than 60%. This was accomplished by a precise...
