Special Issue Information

Dear Colleagues,                

The interaction of light and matter has been a central element in revolutionizing the science and technology of modern society in an unprecedented way. Thus, the field of the control of interactions between light and matter is of vital importance since it covers important scientific aspects concerning physics, chemistry, and engineering. Moreover, it offers an irreplaceable method with which to investigate and connect light–matter interaction phenomena to related applications of novel materials at the nanoscale. The field continues to grow at a very rapid pace, which brings many new exciting discoveries almost every day. To attract broad attention to the control of light and matter interactions at the nanoscale, we are organizing this Special Issue.

The Special Issue on the control of light–matter interaction at the nanoscale aims to highlight recent computational and theoretical advancements related to light–matter interaction and its control at the nanoscale in relevant research areas within physics, chemistry, and materials science; however, contributions of novel experimental results are also highly welcome. The topics of the Special Issue include, but are not limited to, the following: macroscopic quantum electrodynamics, quantum control of nanoscale systems, plexcitonics, ultrashort intense laser–matter interaction, active and passive control of light by matter, nonlinear and quantum optics, cavity optomechanics, optical applications of quantum technologies, quantum sensing, and energy as well as charge transfer at the nanoscale.

Manuscripts can be submitted in the following formats: full research papers, communications, and reviews.

The coupling between the quantum dots (QDs) and silicon-based microdisk resonator facilitates enhancing the light–matter interaction for the novel silicon-based light source. However, the typical circular microdisks embedded with Ge QDs still have several issues, such as wide spectral bandwidth, difficult mode selection, and low waveguide coupling efficiency. Here, by a promising structural modification based on the mature nanosphere lithography (NSL), we fabricate a large area hexagonal microdisk array embedded with Ge QDs in order to enhance the near-infrared light emissions by a desired whispering gallery modes (WGMs). By comparing circular microdisks with comparable sizes, we found the unique photoluminescence enhancement effect of hexagonal microdisks for certain modes. We have confirmed the WGMs which are supported by the microdisks and the well-correlated polarized modes for each resonant peak observed in experiments through the Finite Difference Time Domain (FDTD) simulation. Furthermore, the unique enhancement of the TE5,1 mode in the hexagonal microdisk is comparatively analyzed through the simulation of optical field distribution in the cavity. The larger enhanced region of the optical field contains more effectively coupled QDs, which significantly enhances the PL intensity of Ge QDs. Our findings offer a promising strategy toward a distinctive optical cavity that enables promising mode manipulation and enhancement effects for large-scale, cost-effective photonic devices.
