摘要：
InP/InGaAsP buried heterostructure lasers for a wavelength of 1.15 mu m with optimized parameters can play an important role as pump sources for blue-upwards conversion fiber lasers. This paper reports the single-step liquid phase epitaxial growth and characterization of a double-channelled substrate InP/InGaAsP buried heterostructure laser diode for a wavelength of 1.15 mu m. Optimum conditions for separate growth of an InGaAsP buried active layer on the double-channelled InP substrate have been obtained. Output powers over 100 mW have been obtained by determining the appropriate cavity length and the reflectivity of the mirror facets. High power single-transverse mode operation and a nearly symmetrical beam of the lasers are advantageous for pumping of fiber lasers.
