Nanostructured Transition Metal Dichalcogenide Multilayers for Advanced Nanophotonics

Battulga Munkhbat et al.

Summary: Transition metal dichalcogenides (TMDs), including semiconducting WS2, in-plane anisotropic ReS2, and metallic TaSe2, TaS2, and NbSe2, have attracted significant attention due to their exceptional optical, excitonic, mechanical, and electronic properties. Nanostructured multilayer TMDs, with their high refractive indices and optical anisotropy, show promise for nanophotonic applications. Advanced nanofabrication strategies, including careful selection of resists for electron beam lithography and etching methods, are discussed, with a specific focus on non-conductive substrates such as SiO2. These TMD-based nanostructures have the potential to impact high-index nanophotonics, plasmonics, and on-chip optical circuits.

Engineering Purcell factor anisotropy for dark and bright excitons in two dimensional semiconductors

Lekshmi Eswaramoorthy et al.

Summary: In this study, we propose a method to enhance the coupling of dark excitons in two-dimensional materials with resonant modes by manipulating the anisotropy of the Purcell factor. We demonstrate the versatility of tapering the sidewalls of a silica micro-disk to selectively couple whispering gallery modes to light emitted from out-of-plane dipoles, relative to in-plane ones, for four representative monolayer TMDCs.

Room-temperature continuous-wave indirect-bandgap transition lasing in an ultra-thin WS2 disk

Junghyun Sung et al.

Summary: In this study, indirect-bandgap transition lasing under continuous-wave excitation at room temperature is demonstrated in an ultra-thin WS2 disk. It is shown that a 50-nm-thick WS2 disk provides sufficient optical gain and whispering gallery modes for lasing action. These results offer a new direction for van-der-Waals-material-based nanophotonics and introduce the possibility for optical devices based on indirect-bandgap materials.

Intrinsic circularly polarized exciton emission in a twisted van der Waals heterostructure

J. Michl et al.

Summary: This article reports the discovery of intrinsic circular polarization in the exciton photoluminescence of a twisted MoSe2/WSe2 heterostructure when driven by a linearly polarized laser. The polarization is not influenced by the incident light polarization, and is present even at zero magnetic field. Interestingly, the application of a perpendicular magnetic field can significantly diminish this effect, indicating a new pyromagnetic symmetry in the structure.

Moire and beyond in transition metal dichalcogenide twisted bilayers

Kha Tran et al.

Summary: Fabricating van der Waals bilayer heterostructures provides a unique physical system with rich electronic and optical properties by stacking two-dimensional layers. The twist-angle between component layers is a key parameter that can control the period of lateral confinement and the nature of excitons, leading to the creation of exotic physical states. This review article focuses on the opto-electronic properties of excitons in transition metal dichalcogenide semiconductor twisted bilayer heterostructures, providing insights into moire excitons and nanoscale mapping of moire superlattice.

All van der Waals Integrated Nanophotonics with Bulk Transition Metal Dichalcogenides

Haonan Ling et al.

Summary: The article introduces the concept of all van der Waals photonics and discusses the potential applications of electronically bulk transition metal dichalcogenide (TMDC) semiconductors in nanoscale and integrated photonics. Bulk TMDCs may potentially outperform conventional 3D semiconductors, leading to smaller devices, more energy-efficient electro-optic modulators, and stronger quantum light-materials interaction. The enhanced optical performance, ease of integration, and wide range of materials selection suggest that bulk TMDCs may complement existing integrated photonics systems.

Summary: Germanium self-assembled nanoislands and quantum dots show great potential for CMOS-compatible optoelectronic integrated circuits, but their photoluminescence intensity is currently lacking. Experimental results demonstrate that the photoluminescence of Ge nanoislands in silicon photonic crystal slabs with hexagonal lattice can be dramatically enhanced, paving the way for a new class of optoelectronic components compatible with silicon technology.
