“…[33] Since the initial report of microcavity lasing, several groups have lowered the lasing threshold by using better polymers [87] and by replacing the silver mirror with a dielectric mirror. [42,86,88] Microcavity lasers have several attractive advantages: they are easy to make; their architecture is similar to that of polymer LED's; and they emit perpendicularly from the substrate plane, which is useful for many applications. Unfortunately, the distance traveled by light during each pass through the gain region is small (<200 nm).…”

Light‐emissive polymers are outstanding laser materials because they are intrinsically “4‐level” systems, they have luminescence efficiencies higher than 60 % even in undiluted films, they emit at colors that span the visible spectrum, and they can be processed into optical quality films by spin casting. The important materials issues are reviewed and the prospects for making polymer diode lasers are discussed.

“…Recently another conjugated polymer, the blue emitting oligofluorene truxene T4 has been reported to exhibit optical loss that is reduced by a third (optical loss coefficient 2.3 cm 1 ) relative to polyfluorene polymers, allowing for development of low threshold (270 W/cm 2 ) DFB lasers [180]. Besides fluorinebased polymers other conjugated polymers widely used for development of lasers are poly(p-phenylene vinylene) (PPV) derivatives [50,79,168,181,182], poly(9-vinylcarbazole) (PVK) [183,184], ladder-type poly(pphenylene) materials (MeLPPP) [185,186].…”

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],

A combined photoluminescence (PL) -detected magnetic-resonance (PLDMR) and thermally stimulated current (TSC) study of defects in wide-band-gap para-phenylene-type semiconductors is described. As TSC probes the density of mobile charge carriers after detrapping and PLDMR reveals the influence of trapped charges on the PL, their combination yields the concentration of traps, their energetic position, and their contribution to PL quenching. The reported trap densities, which are 2×1016 for the polymer and 1×1014 cm−3, for the oligomer, are the lowest reported for para-phenylene-type materials.
