Temperature effects in metal-clad semiconductor nanolasers

open access: yesNanophotonics, 2015
As the field of semiconductor nanolasers becomes mature in terms of both the miniaturization to the true sub-wavelength scale, and the realization of room temperature devices, the integrated treatment of multiple design aspects beyond pure ...

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

open access: yesNanophotonics
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 ...

Dissipative Josephson effect in coupled nanolasers

open access: yesNew Journal of Physics, 2021
Josephson effects are commonly studied in quantum systems in which dissipation or noise can be neglected or do not play a crucial role. In contrast, here we discuss a setup where dissipative interactions do amplify a photonic Josephson current, opening a

Stress Accumulation Induced by Ion Exchange for Synchronous Modulation of Mode and Wavelength in Microlasers. [PDF]

open access: yesAdv Sci (Weinh)
This work demonstrates a paradigm‐shifting strategy to simultaneously achieve broadband wavelength tunability and single‐mode control within a single perovskite microwire structure. Using a facile heating‐assisted solid–solid anion‐exchange strategy, we synthesized phase‐pure CsPbClxBr3‐x microwires that exhibit the widest reported continuous lasing ...

Multiple Bound States in the Continuum in Deep‐Subwavelength Nonlocal Polar Dielectric Nanoparticles [PDF]

open access: yesNanophotonics
Spatial dispersion in polar‐dielectric core–shell nanoparticles enable multiple deep‐subwavelength bound states in the continuum through longitudinal‐transverse hybrid modes. By suppressing radiative damping at finite geometrical parameters, these nonlocality‐induced BICs provide a compact platform for high Q light confinement, enhanced light–matter ...

On‐Chip Monolithically Integrated Ultraviolet Low‐Threshold Plasmonic Metal‒Semiconductor Heterojunction Nanolasers [PDF]

open access: yesAdvanced Science, 2023
The metal‒semiconductor heterojunction is imperative for the realization of electrically driven nanolasers for chip‐level platforms. Progress in developing such nanolasers has hitherto rarely been realized, however, because of their complexity in ...

Anapole nanolasers for mode-locking and ultrafast pulse generation [PDF]

open access: yesNature Communications, 2017
Here, the authors introduce the concept of nanocscale lasers based on a tightly confined anapole mode. Using first-principle calculations they show that the superposition of internal modes can generate radiation-less states that are scattering free ...

Harnessing coupled nanolasers near exceptional points for directional emission. [PDF]

open access: yesSci Adv
Tailoring the losses of optical systems within the frame of non-Hermitian physics has appeared very fruitful in the last few years. In particular, the description of exceptional points (EPs) with coupled resonators have become widespread.

Defect-evolved quadrupole higher-order topological nanolasers [PDF]

open access: yesNature Communications
Topological photonics have been garnering widespread interest in engineering the flow of light with topological ideas. Strikingly, the recent introduction of higher-order topological insulators has generalized the fundamental framework of topological ...
