摘要：

An analysis of a surface emitting distributed-feedback quantum cascade laser（DFB QCL） based on a surface-plasmon waveguide is presented.The second-order grating realized by the sole patterning of the top metal provides strong feedback.The analysis is based on a coupled-mode theory derived from exact Floquet-Bloch solutions of the infinite periodic structure.The surface outcoupling efficiency and threshold gain for the optimized device design are 43%and 12 cm;,respectively,which represent great improvements on the conventional dielectric waveguide based DFB QCL with typical values of 17.5%and 20 cm;.
