Femtosecond laser direct writing of single mode polymer micro ring laser with high stability and low pumping threshold

Abstract: We have demonstrated an optically pumped polymer microring laser fabricated by two photon polymerization (TPP) of SU-8. The gain medium is an organic dye (Rhodamine B) doped in SU-8, and the laser cavity is a double coupled microring structure. Single mode lasing was obtained from the two coupled rings each with 30 µm and 29 µm radii using Vernier effect. Low laser threshold of 0.4 µJ/mm(2) is achieved using 1 µm wide polymer waveguides and the quality factor is greater than 10(4) at 612.4 nm wavelength. The l… Show more

“…This factor was also found for regular, non-split polymeric micro-disks and is mainly attributed to the effect of photo-bleaching and aggregation of dye molecules originating from the high incident power in the two photon absorption process. 12,[48][49][50] Let us first focus on implementation, precision, and reproducibility of our tuning experiments. Starting at the initial value d initial = 2580 nm, the gap has been gradually reduced by applying increasing substrate elongation in steps of ∆x = 50 µm up to a maximum of ∆x max = 800 µm.…”

“…This is motivated by a desire to tailor the properties of components like interconnects, waveguides or cavities to specific but varying requirements. Due to their versatility and flexibility, organic materials are highly promising candidates for achieving this goal and a number of fabrication methods such as direct laser writing by two-photon polymerization [1][2][3] or direct circuit printing [4] have been suggested and are now developing rapidly.…”

Due to their unique molecular structure, which comprises a highly fluorescent chromophore unit surrounded by a protective molecular bumper (β-barrel), [5,6] the chromophores are well protected from their surrounding and FPs are largely immune to concentration quenching.…”
