- 論文の詳細を見る
Ink-jet-printed organic distributed feedback (DFB) lasers are realized by employing light-emitting copolymer and suitable organic solvents to meet the demands of printability and optical amplification in a nanopatterned conjugated polymer slab waveguide. We demonstrate the accurate lateral positioning of ink-jet-printed patches of the gain material on a polymer substrate with 500\times 500 μm2 grating areas. We also printed patches of large lateral dimension of 6 mm2 on a silica grating. The high uniformity of the film thickness leads to a laser wavelength variation of less than 3 nm over the whole area.
