Abstract

This letter describes the design, fabrication, and experimental results of a micro solid polymer dye laser designed on the basis of a guided mode resonant grating (GMRG). The resonant condition of GMRG includes the second-order resonance of the distributed feedback cavity. A surface laser emission was obtained in a patterned region by the pulsed-laser pumping. The grating was fabricated by the electron beam lithography and the fast atom beam etching. Dye (rhodamine 6G)-doped poly(methylmethacrylate) was spin-coated on the grating. The laser oscillation occurred in the direction vertical to the grating plane with a sharp peak (Q -value ∼1271) in a single mode designed by the GMRG analysis.
