Liquid-crystal lasers are a burgeoning area in the field of soft-matter photonics that may
herald a new era of ultrathin, highly versatile laser sources. Such lasers encompass a …

We present a critical review of semiconducting/light emitting, liquid crystalline materials and
their use in electronic and photonic devices such as transistors, photovoltaics, OLEDs and …

The introduction of chirality, ie, the lack of mirror symmetry, has a profound effect on liquid
crystals, not only on the molecular scale but also on the supermolecular scale and phase. I …

Tuning the wavelength of a laser emission by mechanical deformation is not as implausible
as it may seem. This communication proves that it can be done with cholesteric liquid crystal …

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 …

Photonic-bandgap materials, with periodicity in one, two or three dimensions, offer control of
spontaneous emission and photon localization,,. Low-threshold lasing has been …

Because of their small mode volume and high Q-factors, optical microresonators are
interesting for applications such as laser sources, active filters and all-optical switches …

We demonstrate a tunable and omnidirectional microlaser in the form of a microdroplet of a
dye-doped, cholesteric liquid crystal in a carrier fluid. The cholesteric forms a Bragg-onion …

The demonstration of the first ruby laser in 1960 led to a revolution in science and
technology. The lasers have significantly influenced the development of new approaches to …

This article presents a review of the lasing and photonic properties of periodic one-
dimensional anisotropic structures with the symmetry of a double helix. Examples are self …
