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 …

An overview on the properties and applications of polymer and inorganic planar 1D photonic
crystals fabricated from solution is provided here. In the last decades, photonic crystals …

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 …

The so-called PT symmetric devices, which feature ε (− x)= ε (x)* associated with parity-time
symmetry, incorporate both gain and loss and can present a singular eigenvalue behaviour …

People working in the world of organic photonics and organic electronics are used to
hearing the following statement: a prerequisite to success in this field is to acquire …

In this review article, we describe the basic principles of random laser operation with
particular emphasis on π‐conjugated, dye‐doped and biologically inspired polymers …

An innovative concept of thin-film organic solid-state laser is proposed, with diffraction-
limited output and a broad tuning range covering the visible spectrum under UV optical …

High-power, diffraction-limited organic solid-state laser operation has been achieved in a
vertical external cavity surface-emitting organic laser (VECSOL), pumped by a low-cost …

Optically pumped lasers based on solution-processed thin-film gain media have recently
emerged as low-cost, broadly tunable, and versatile active photonics components that can fit …

Abstract A series of unsymmetrical 1, 3-diaryl-β-diketones 1–6 displaying molecular
conformation-dependent fluorescence quantum yields have been synthesized. Crystals with …
