摘要：

Investigation of epitaxial layer structures has yielded narrow ridge waveguide structure lasers capable of coupling high optical power into single mode fiber (SMF). High optical power of well over 60 mW in SMF was obtained for a 2-mu-m-wide ridge waveguide laser with guided SCH epitaxial structure. Calculated results indicate that the stringent limit imposed on 0.98-mu-m wavelength detuning is relaxed for such high optical power coupled into SMF. The present 0.98-mu-m strained quantum well lasers thus show considerable promise as a practical low-noise pumping source for Er-doped optical fiber amplifiers.
