Low-Dimensional Nanomaterials for Advanced Photonics and Optoelectronics

Dear Colleagues,

Over the past two decades, low-dimensional nanomaterials have seen remarkable progress in photonics and optoelectronics. The pursuit of stronger light–matter interactions at the nanoscale has driven the development of quantum dots, nanowires, carbon nanotubes, and two-dimensional layered materials such as graphene, transition metal dichalcogenides, MXenes, and perovskites. These materials exhibit strong quantum confinement, large exciton binding energies, and tunable band structures.

Specifically, nanoscale engineering has already shown its potential to transform the performance, stability, and integration density of photodetectors, light emitters, and on-chip photonic circuits. Moreover, low-dimensional nanomaterials often retain functionality under extreme environments—radiation, temperature extremes, or high pressure—making them attractive for aerospace, nuclear, and deep-sea applications.

Low-Dimensional Nanomaterials for Advanced Photonics and Optoelectronics is a Special Issue that seeks to highlight recent advancements in the synthesis, characterization, and device integration of these materials. Particular attention will be given to the roles of dimensionality, heterostructure assembly, and defect engineering in tailoring optical responses. Topics of interest range from exciton–polariton physics and ultrafast nonlinear optics to practical challenges such as large-area fabrication and CMOS-compatible processing. This Special Issue aims to provide comprehensive insights into how low-dimensional nanomaterials are shaping next-generation photonic and optoelectronic systems. We invite you to share your valuable contributions.

Specific topics include, but are not limited to, the following:

• Device-relevant light–matter interactions;
• Nonlinear and ultrafast photonic devices;
• Photodetectors;
• Light emitters and lasers;
• Integrated photonics and modulators;
• Quantum photonic devices;
• Emerging materials for applications;
• Fabrication, integration, and reliability;
• Performance under extreme environments;
• Characterization for device development.
