Article Abstract
Surface plasmon (SP)-induced spectral hole burning (SHB) at the silver-dielectric interface is investigated theoretically. We notice a typical lamb dip at a selective frequency, which abruptly reduces the absorption spectrum of the surface plasmons polaritons (SPP). Introducing the spontaneous generated coherence (SGC) in the atomic medium, the slope of dispersion becomes normal. Additionally, slow SPP propagation is also noticed at the interface. The spectral hole burning dip is enhanced with the SGC effect and can be modified and controlled with the frequency and intensity of the driving fields. The SPP propagation length at the hole-burning region is greatly enhanced under the effect of SGC. A propagation length of the order of 600 µm is achieved for the modes, which is a remarkable result. The enhancement of plasmon hole burning under SGC will find significant applications in sensing technology, optical communication, optical tweezers and nano-photonics.

We demonstrate a single-polarization single-frequency Yb-doped fiber laser operating at 1156 nm using a 10-m-long unpumped Yb-doped fiber (YDF) as a dynamic saturable absorber (SA). Leveraging spatial hole-burning-induced refractive index modulation, a self-adaptive Bragg grating with sub-MHz bandwidth is formed, enabling ultranarrow linewidth single-longitudinal-mode lasing. The linear cavity design with bidirectional pumping achieves an output power of 20.

Rare-earth emitters in solids are well suited for implementing efficient, long-lived quantum memory coupled to integrated photonics for scalable quantum technologies. They are typically introduced as dopants in a solid-state host, but this introduces disorder and limits the available density of emitters. Stoichiometric materials can offer high densities with narrow optical linewidths.

The physics of the heat-trapping properties of CO[Formula: see text] were established in the mid-19th century, as fossil fuel burning rapidly increased atmospheric CO[Formula: see text] levels. To date, however, research has not probed when climate change could have been detected if scientists in the 19th century had the current models and observing network. We consider this question in a thought experiment with state-of-the-art climate models.

The disorder is introduced along one spatial axis of the metasurface by pseudo-randomly varying the width of its resonant ridge antennas. Compared to a quantum-cascade (QC) VECSEL based on a uniform metasurface, the disordered structure supports much more localized transverse modes with reduced spatial overlap within the QC gain material.

Strong light-matter interactions and tunable optical cross-sections of gold nanorods (AuNRs) offer unique alternatives to traditional atomic- and molecular-base absorptive elements for filters and polarizers. However, harnessing these properties in a large area or bulk components remains a significant challenge, largely due to limited options for affordable fabrication of large quantities of AuNRs with narrow polydispersity. Herein, these challenges are overcome with the recent large-volume synthesis of highly uniform AuNRs, spectral hole burning, and thermoforming of polymer nanocomposites.
