Photonic neuromorphic computing using symmetry-protected zero modes in coupled nanolaser arrays [PDF]

open access: yesNature Communications
Photonic neuromorphic computing has emerged as a promising approach toward energy-efficient artificial neural networks (ANN). Nanolasers, in particular, have become attractive candidates due to their ultra-low power consumption and intrinsic nonlinear ...

Exceptional points with waveguide-coupled nanolasers [PDF]

open access: yesEPJ Web of Conferences
Exceptional points (EPs) attract lots of attention due to the richness of the phenomenology associated to their presence in the complex eigenspectrum of coupled non-Hermitian systems.

Colloidal-quantum-dot nanolaser oscillating at a bound-state-in-the-continuum with planar surface topography for a high Q-factor [PDF]

open access: yesNanophotonics
Solution-based optical gain materials offer a cost-effective path to coherent light sources. Further, bound states in the continuum (BICs) have garnered great interest owing to their diverging quality (Q) factors.

Zero Crosstalk Regime Direct Modulation of Mutually Coupled Nanolasers

open access: yesIEEE Photonics Journal, 2017
The modulation properties of dually modulated mutually coupled nanolasers have been analysed using rate equations which include the Purcell cavity-enhanced spontaneous emission factor F and the spontaneous emission coupling factor β.

Lasing Threshold in Nanolasers with Extreme Dielectric Confinement

open access: yes, 2023
Nanolasers based on emerging dielectric cavities with deep sub-wavelength optical confinement may offer an unprecedented light-matter coupling rate, near-unity spontaneous emission factor, and ultra-low threshold current.

Spontaneous emission noise resilience of coupled nanolasers [PDF]

open access: yes, 2023
We investigate the spontaneous emission noise resilience of the phase-locked operation of two delay-coupled nanolasers. The system is modeled by semi-classical Maxwell–Bloch rate equations with stochastic Langevin-type noise sources.

Quantum Langevin approach for superradiant nanolasers

open access: yesNew Journal of Physics, 2021
A new approach for analytically solving quantum nonlinear Langevin equations is proposed and applied to calculations of spectra of superradiant lasers where collective effects play an important role.

Two-dimensional plasmonic waveguides for nanolasing and four-wave mixing

open access: yesNew Journal of Physics, 2019
Plasmonic waveguides are an essential element of nanoscale coherent sources, including nanolasers and four-wave mixing (FWM) devices. Here we report how the design of the plasmonic waveguide needs to be guided by the ultimate application.

Deep reinforcement learning empowers automated inverse design and optimization of photonic crystals for nanoscale laser cavities

open access: yesNanophotonics, 2023
Photonics inverse design relies on human experts to search for a design topology that satisfies certain optical specifications with their experience and intuitions, which is relatively labor-intensive, slow, and sub-optimal.
