1.3 μm solid-state plastic lasers were fabricated using fluorinated-polyimide as the host matrix of the active waveguide doped with near-infrared organic dye, IR26. DFB lasing oscillation as well as FP mode one is realized using photo-nanoimprint lithography.
Previously, we proposed novel pumping scheme 'quasi mode coupling (QMC)' for fiber-top-pumping. Since QMC reuires a four layered (dual core) structures, demonstrated QMC-distributed feedback (DFB) dye lasers requires complicated fabrication process with spin-coating. In this report, we demonstrated simple fabrication of QMC-DFB dye lasers due to the 'print-like-fabrication' at first time.
In this paper, we propose an evaluation method for device parameters of solid-state organic lasers. Using a self-written active (SWA) waveguide technique, a Fabry-Perot (FP)-type organic laser with a channel waveguide structure was fabricated, in which the cavity length and the feedback efficiency can be easily controlled. The lasing threshold of the fabricated organic laser showed a monotonic decrease...
A polymer-based gain waveguide structure, ldquoself-written active (SWA) waveguiderdquo, was invented. In the SWA waveguide, optical amplification and Fabry-Perot laser oscillation were demonstrated. The SWA waveguide devices will be considerable components for the integrated optoelectronics.
