: The advance of topological photonics has heralded a revolution for manipulating light as well as for the development of novel photonic devices such as topological insulator lasers. Here, we demonstrate topological lasing of circular polarization in a polymer-cholesteric liquid crystal (P-CLC) superlattice, tunable in the visible wavelength regime. By use of the femtosecond-laser direct-writing and self-assembling techniques, we establish the P-CLC superlattice with a controlled mini-band…

Topological photonic crystal nanocavity laser

Topological edge states exist at the interfaces between two topologically distinct materials. The presence and number of such modes are deterministically predicted from the bulk band topologies,

Room-temperature lasing from nanophotonic topological cavities

This work proposes and demonstrates experimentally active nanophotonic topological cavities incorporating III–V semiconductor quantum wells as a gain medium in the structure and shows room-temperature lasing with a narrow spectrum, high coherence, and threshold behaviour, a step towards topologically controlled ultrasmall light sources with nontrivial radiation characteristics.

Lasing at topological edge states in a photonic crystal L3 nanocavity dimer array

Investigation of TESs in a PhC nanocavity array in the Su–Schrieffer–Heeger model finds evidence of lasing from sources even smaller than the wavelength of light, which could enable further minimising of photonic devices and have applications for quantum computing.

Nonlinear light generation in topological nanostructures

This study reports the observation of a third-harmonic signal from a topologically non-trivial zigzag array of dielectric nanoparticles and the demonstration of strong enhancement of the nonlinear photon generation at the edge states of the array.

One-dimensional planar topological laser

Abstract Topological interface states are formed when two photonic crystals with overlapping band gaps are brought into contact. In this work, we show a planar binary structure with such an interface

Low-threshold topological nanolasers based on the second-order corner state

A team of Chinese researchers have developed a topological laser made from a two-dimensional photonic crystal nanocavity slab with a lasing threshold of about one micro-watt and high spontaneous emission coupling factor of 0.25, which is comparable to the performance of conventional semiconductor lasers.

Topological hybrid silicon microlasers

Topological effects, first observed in condensed matter physics, are now also studied in optical systems, extending the scope to active topological devices, and Zhao et al. combine topological physics with non-Hermitian photonics, demonstrating a topological microlaser on a silicon platform.
