“…deep‐tissue imaging) and probably in the near future plasmonics (discussed in the next section) will continue to motivate research towards efficient deep‐red or IR gain materials and lasers. Lasing operation has been reported160 from 890 to 930 nm in a DFB structure, or even at 970 nm in a Fabry–Perot configuration, with a commercial dye (LDS 950) doped in a fluorinated polyimide waveguide 161. The optical gain is low in this case (14 cm −1 ) and the lasing threshold relatively high (600 µJ cm −2 ).…”

Organic solid-state lasers are reviewed, with a special emphasis on works published during the last decade. Referring originally to dyes in solid-state polymeric matrices, organic lasers also include the rich family of organic semiconductors, paced by the rapid development of organic light emitting diodes. Organic lasers are broadly tunable coherent sources are potentially compact, convenient and manufactured at low-costs. In this review, we describe the basic photophysics of the materials used as gain media in organic lasers with a specific look at the distinctive feature of dyes and semiconductors. We also outline the laser architectures used in state-of-the-art organic lasers and the performances of these devices with regard to output power, lifetime, and beam quality. A survey of the recent trends in the field is given, highlighting the latest developments in terms of wavelength coverage, wavelength agility, efficiency and compactness, or towards integrated low-cost sources, with a special focus on the great challenges remaining for achieving direct electrical pumping. Finally, we discuss the very recent demonstration of new kinds of organic lasers based on polaritons or surface plasmons, which open new and very promising routes in the field of organic nanophotonics.

Organic dyes have been used as gain medium for lasers since the 1960s, long before the advent of today's organic electronic devices. Organic gain materials are highly attractive for lasing due to their chemical tunability and large stimulated emission cross section. While the traditional dye laser has been largely replaced by solid-state lasers, a number of new and miniaturized organic lasers have emerged that hold great potential for lab-on-chip applications, biointegration, low-cost sensing and related areas, which benefit from the unique properties of organic gain materials. On the fundamental level, these include high exciton binding energy, low refractive index (compared to inorganic semiconductors), and ease of spectral and chemical tuning. On a technological level, mechanical flexibility and compatibility with simple processing techniques such as printing, roll-to-roll, self-assembly, and soft-lithography are most relevant. Here, the authors provide a comprehensive review of the developments in the field over the past decade, discussing recent advances in organic gain materials, which are today often based on solid-state organic semiconductors, as well as optical feedback structures, and device fabrication. Recent efforts toward continuous wave operation and electrical pumping of solid-state organic lasers are reviewed, and new device concepts and emerging applications are summarized.

“…11b. In another study on the fluorinated polyimide polymer host, laser emission in the nearinfrared at a wavelength around 970 nm was obtained from a planar waveguide doped with the laser dye 5,6-dichloro-2[8-(p-dimethylaminophenyl)-2,4-neopentylene-1,3,5,7-octatetraenyl]-3-ethylbenzothiazolium perchlorate (LDS950) [119]. One attractive feature of the FPI host that was of key importance for the realization of these lasers was the elimination of the C-H vibrational bond absorption at their emission bands around 1.3 μm and 1 μm, respectively, by the exchanged C-F bonds.…”

“…Frequently used polymer hosts are MMA-based materials including poly(methyl methacrylate) (PMMA) [112,113], copolymer compositions such as those of MMA with the monofunctional monomer 2-hydroxyethyl methacrylate (HEMA) [114][115][116][117][118] as well as of pentaerythritol tri-acrylate (PETA) with benzyl acrylate (BA) [86,87]. Other organic materials that have been studied as hosts for dyes and demonstrated laser devices include fluorinatedpolyimide [119], polystyrene (PS) [120,121], the photopolymerizable resins KAYARAD DF-803N [97][98][99][100] and PAK-01-CL [85,86], SU8 [40,68,122], and poly(1-vinyl-2-pyrrolidone) (PVP) [123].…”

Solid-state organic amplifiers and lasers are attractive for hybrid integration due to their compatibility with different material platforms, straightforward processing, and possibility to optimize easily their optical and electronic properties by molecular engineering. Advances in the gain medium design and synthesis in combination with new resonator architectures led to tremendous improvements in temporal and spectral properties, lifetime stability, gains produced and operating threshold powers, which triggered interest in their use for a broad range of integrated photonic applications. In this contribution, the current state-of-the-art in the field of organic solid-state amplifiers and lasers is reviewed from the aspects of fabrication technology, gain materials, and device performance. Furthermore, examples of the progress of this technology from a laboratory curiosity to one that demonstrates practical integrated photonic applications are highlighted. An outlook is also provided on research areas and applications that are likely to shape further developments of this technology. (Figure reprinted from [296],
