Dipole nanolaser

Physical Review A, 2005
A "dipole" laser is proposed consisting of a nanoparticle and a two-level system with population inversion. If the threshold conditions are fulfilled, the dipole interaction between the two-level system and the nanoparticle leads to coherent oscillations in the polarization of the particles, even in the absence of an external electromagnetic ...

Rolling‐Enabled Nonplanar Heterogeneous Integration for Polarization‐Diverse Nanolasers on Silicon Photonics

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
Rolling‐enabled transfer printing introduces mechanical orientation as a new degree of freedom for heterogeneous silicon photonics. A conventional TE‐like photonic‐crystal nanobeam laser is mechanically rotated by 90° to selectively couple with the TM‐like mode of a silicon waveguide, enabling polarization‐diverse functionality without redesigning the ...

High-Density and Uniform Lead Halide Perovskite Nanolaser Array on Silicon

, 2016
The realization of high density and highly uniform nanolaser arrays in lead halide perovskite is quite challenging, especially on silicon. Herein, we demonstrate a simple way to form lead halide nanolaser array on silicon chip with high density and ...

Giant photon bunching, superradiant pulse emission and excitation trapping in quantum-dot nanolasers

Nature Communications, 2016
Classical light sources are characterized by their intensity and coherence, whereas quantum light sources are described by photon correlations. Here, the authors provide a connection between the two for the case of superradiant emission from quantum dots

Opportunities of Semiconducting Oxide Nanostructures as Advanced Luminescent Materials in Photonics

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
The review discusses the challenges of wide and ultrawide bandgap semiconducting oxides as a suitable material platform for photonics. They offer great versatility in terms of tuning microstructure, native defects, doping, anisotropy, and micro‐ and nano‐structuring. The review focuses on their light emission, light‐confinement in optical cavities, and

High‐Power Continuous‐Wave Optical Waveguiding in a Semiconductor Nanowire

Advanced Photonics Research, Volume 7, Issue 9, September 2026.
An in‐line fiber–nanowire–fiber configuration provides efficient coupling of 1550 nm continuous‐wave light into and out of a single CdS nanowire. The output power increases linearly with input power, reaching 1.8 W and corresponding to a guided power of 2.5 W, demonstrating watt‐level continuous‐wave optical waveguiding in a subwavelength semiconductor

Theory of nanolaser devices: Rate equation analysis versus microscopic theory [PDF]

, 2013
A rate equation theory for quantum-dot-based nanolaser devices is developed. We show that these rate equations are capable of reproducing results of a microscopic semiconductor theory, making them an appropriate starting point for complex device ...

Spaser as a biological probe

Nature Communications, 2017
Advanced diagnostic probes are required for monitoring disease progression. Here Galanzhaet al. demonstrate a 22 nm plasmonic nanolaser to serve as a super-bright, biocompatible probe capable of generating stimulated emission directly inside living cells
