Optofluidic evanescent dye laser based on a distributed feedback circular grating
We demonstrate an optofluidic evanescent laser based on a solid circular distributed feedback grating with the dye solution acting as the cladding layer. The laser mode is confined within the grating and experiences optical gain via the interaction between its evanescent component with the dye solution. Above a pump energy of 9.5 J /pulse, the laser exhibited single mode operation at 571 nm. St...
متن کاملFabrication of Circular Grating Distributed Feedback Dye Laser by Nanoimprint Lithography
Within recent years the development of polymer dye lasers has progressed to higher levels of performance and functionality. The most attractive advantages of polymer dye lasers include low-cost processing, wide choice of emission wavelengths, and easy fabrication on flexible substrates. Several waveguide dye lasers have been studied with emission wavelengths ranging from ultraviolet to near inf...
متن کاملA Nanoimprinted Microfluidic Dye Laser
We present a polymer based microfluidic dye laser suitable for integration into micro total analysis systems, fabricated by nanoimprint lithography (NIL) [1] in the thermoplastic polymer COC (cyclo olefin copolymer) [2]. The device (se figure 1 and 2) consists of microfluidic channels, with sizes ranging from several mm down to 16 μm, and optical waveguides, all fabricated in one single NIL ste...
متن کاملSingle mode optofluidic distributed feedback dye laser.
Single frequency lasing from organic dye solutions on a monolithic poly(dimethylsiloxane) (PDMS) elastomer chip is demonstrated. The laser cavity consists of a single mode liquid core/PDMS cladding channel waveguide and a phase shifted 15th order distributed feedback (DFB) structure. A 1mM solution of Rhodamine 6G in a methanol and ethylene glycol mixture was used as the gain medium. Using 6 na...
متن کاملOrganic solid-state distributed feedback dye laser with a nonmorphological modification grating
We report an organic solid-state distributed feedback laser consisting of an organic active layer and a Bragg grating without morphological change. The active layer consists of 4-~dicyanomethylene!-2-methyl-6-~4-dimethylaminostryl!-4H-pyran as a laser dye, tris~8hydroxyquinoline! aluminum as a host, and poly~methyl methacrylate! as a binder. The threshold and linewidth of the laser are 400 mJ/c...
