Researchers from Russia and China have for the first time conducted calculations of the behavior of large sets of nanocylinders and other objects interacting with light and electromagnetic waves. This was reported at the MIPT Center for Scientific Communication.
The research results can help in creating unique nanophotonic and optical devices.
You can imagine an optical chip where chains of nanocylinders of different lengths are located in different parts of it. Each chain will act as a filter or resonator with unique, precisely defined parameters, which allows for complex optical signal processing on a single crystal. Controlling the movement of light in chains of nanoelements can be used to create waveguides and switches on photonic integrated circuits.
The most promising material is considered to be structures made of multiple nanocylinders — parallel rods made of glass or silicon. With a certain number, thickness, and arrangement, their combinations begin to interact with radiation at certain frequencies. This makes them interesting for the development of various optical devices.
Russian and Chinese scientists have developed a combined approach taking into account the collective and individual features of the interaction of cylinders with light.
We often study idealized infinite structures, but real devices are always finite. Our work built a bridge between these worlds and showed how amazing collective optical effects, such as perfect transparency at certain frequencies, gradually "turn on" as elements are added to the chain.
