A two-dimensional(2D) distributed feedback(DFB) structure is fabricated on dye-doped sol-gel derived hybrid zirconia films by soft lithography.The Q-switched Nd:YAG laser(λ = 532 nm) is used to pump these structures.The lasing emissions of the gain medium doped with Rhodamine 6G(Rh6G) in two perpendicular directions are shown,and the threshold pump energy is measured.
