Because of long‐range order and high chemical purity, organic crystals have exhibit unique
properties and attracted a lot of interest for application in solid‐state lasers. As optical gain …

Modal gain coefficient is a key figure of merit for a laser material. Previously, net modal gain
coefficients larger than a few thousand cm–1 were achieved in II–VI and III–V semiconductor …

The report on a study of laser emission from a conceptually new organic material based on
transparent wood (TW) with embedded dye Rhodamine 6G molecules is presented in this …

With their exceptional optoelectronic properties, CsPbBr3 perovskite nanocrystals (NCs) are
promising materials for light‐emitting devices. Elucidating their stimulated emission …

We establish an efficient strategy to optimize the performance of dye-doped host materials
consisting of analyzing in a systematic way the dependence of their Amplified Spontaneous …

Active waveguides with high surface roughness due to phase separation in polymer blends
can sustain wave-guided coherent random lasing, paving way to the development of …

The Variable Stripe Length (VSL) method is a very popular tool to measure the optical gain
in thin film active devices. However, over the last decade experimental and theoretical …

Second‐order distributed feedback (DFB) resonators are widely used for thin‐film lasers as
they combine low lasing thresholds with ease of manufacturing. Here, the grating design …

One of the major barriers for a widespread commercial uptake of silicon nitride photonic
integrated circuits for cost-sensitive applications is the lack of low-cost monolithically …

We describe herein the synthesis and characterization of a thiophene‐based donor‐
acceptor system, namely (E)‐2‐(4‐nitrostyryl)‐5‐phenylthiophene (Th‐pNO2), which was …
