“…To address lab-on-chip applications that do not necessarily require laser light integration of OLEDs or ASE sources with microfluidic devices represents a convenient solution [299][300][301]. In a more sophisticated approach amongst those reported an OLED was integrated into a low-order mode channel waveguide such that its active layers formed the waveguide core [302].…”

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],

“…Tris-(8-hydroxy quinoline) aluminium (Alq 3 ) was used as host for DCM compound in most of the cases due to the compatibility of the energy levels. [8][9][10] The smallest excitation threshold energy of amplified spontaneous emission which has been obtained is 3 μJ/cm2 at 2 wt% of DCM molecules in Alq 3 matrix. 11 Further increase of dye concentration reduce photoluminescence quantum yield due to large intermolecular interaction wherewith increase threshold value of amplified spontaneous emission.…”

4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran (DCM) is well known red laser dye which can be used also in solid state organic lasers. The lowest threshold value of amplified spontaneous emission was achieved by doping 2wt% of DCM molecule in tris-(8-hydroxy quinoline) aluminium (Alq 3 ) matrix. Further increase of dye concentration also increases threshold value. It is due to large intermolecular interaction which reduce photoluminescence quantum yield. Compounds with small intermolecular interaction and which exhibit similar amplified spontaneous properties as DCM could be useful for solid state organic lasers.In the work photoluminescence and amplified spontaneous emission properties of two DCM derivatives in poly(methyl methacrylate) (PMMA) matrix were investigated. Bulky trityloxyethyl groups are attached to the donor part of investigated molecules. These groups reduce intermolecular distance wherewith reduce photoluminescence quenching. More than one order of magnitude lower excitation threshold energy of the amplified spontaneous emission was achieved in doped polymer films with investigated compound in comparison to doped polymer with DCM. It means that the investigated compound is more perspective as a laser material compared to previously study.

“…Organic light emitting diodes can be integrated [5] but electrical interconnects are needed. The use of optically pumped light sources [6] and external photodetectors in the console results in a chip with optical and fluidic interfaces only [7]. Especially lasers are well suited for sensing because of their narrow spectral width and high output energy.…”

For sensing with lab-on-chip systems, the use of highly integrated photonic components is a key ingredient for high sensitivity and short response time. Here, we present the efficient integration of organic semiconductor distributed feedback lasers based on Alq 3 :DCM and deep ultraviolet induced waveguides into a Poly(methyl methacrylate) (PMMA) substrate. The optimized coupling of laser light from the organic semiconductor lasers into the waveguides is discussed. On-chip coupling of laser light at 645 nm to waveguides is demonstrated. Utilizing mass production technologies and simple processes with only a few different materials paves the way for low-cost all-organic chips. In particular, a specific sensing concept is introduced: deep ultraviolet induced waveguides and nanostructured phospholipid gratings, which are bottom-up assembled using Dip-Pen Nanolithography, are combined to form a grating coupler with a grating period of 700 nm. Light of different wavelength is decoupled under different angles by the grating coupler to demonstrate its functional capability. Biosensing with this device is discussed based on a model system.
