Anapole lasers made of semiconductors that form energy storage nanodisks can be used as an energy source for nanoscale optics in silicon-compatible platforms. Researchers at King Abdullah University (KAUST) said the laser can be made small enough to fit inside a computer circuit board while retaining its ability to form and control laser pulses to manipulate data such as data switches, biomedical implants Things and solar panels and other things. In the anapole state, the laser does not radiate energy in any direction and binds the light within the nanodisk. Andrea Fratalocchi, an associate professor at KAUST, said: "The challenge of lowering the light source to the nanometer scale is that it begins to radiate energy strongly in all directions, which is almost beyond control." Researchers have developed a nanoscale laser based on the closely anapole mode. By exploiting the non-radiative nature of the anapole state, they are able to design nanostructures based on InGaAs nanodisks as a source of silicon with unique optical properties. Utilizing the anapole mode's near-field characteristics, the team demonstrated a spontaneous polarization nanolaser capable of coupling light into waveguide channels at 4 orders of magnitude greater intensity than traditional nanospectrometers. In addition, the team was able to generate ultra-fast (100 femtosecond) pulses by locking several anapoles in a spontaneous mode. Based on the simulation of the photon's quantum electrodynamics, the researchers showed that the photophysical interactions in nanoseeds emitted at anapole frequencies produce surprisingly stable states in which light energy is strongly concentrated within the anapole and propagated in the nanostructure Outside the sub-wavelength region to achieve instantaneous transmission. This "anapole nano laser" can be used in a range of applications, from efficient energy coupling to ultra-fast pulse generation without the need for external design elements. Fratalocchi pointed out that the observer does not seem to see this nanolaser until it is disturbed by nearby objects. Therefore, arranging the cylindrical light sources in a loop may result in a chain reaction of light emission, which can be adjusted down to the femtosecond (fs) pulse time. "You can think of this laser as an energy bin, and once it is on, it stores the light until you want to collect the light without losing it," he said. Anapole nanolasers provide a useful platform for monolithically integrated silicon photon sources for advanced and efficient nanoscale circuits. The team constructed a model that shows that integrating different anapole nanolasers can produce oscillating dynamics for reproducing similar brain activities at low cost, such as machine learning and memory retrieval. The research has been published in the Nature issue of Nature Communications magazine.
