New technique shows excellent potential for developing advanced photonic devices

Photonics can be defined as the science of exploiting light. It has numerous applications in contemporary electronics, like health-based devices, semiconductors, and information technology.

Therefore, scientists across the world have been working to identify innovative methods to drive developments in the area of photonics. However, the difficulty lies in improving the “photon generation” process as required, which is very important for all applications based on photonics.

In a new research published in the Nano Letters journal, a research team from Daegu Gyeongbuk Institute of Science and Technology (DGIST), under the guidance of Professor J. D. Lee, designed an innovative mechanism to increase the efficiency of photon conversion in two-dimensional (2D) materials.

The researchers accomplished this feat by analyzing a technique known as “nonlinear second-harmonic generation” (SHG)—a kind of optical process in which interactions occur between a nonlinear material and two photons with the same level of frequency. Following this, a new photon that has double the energy is produced, thereby resulting in frequency doubling.
