Researchers Make Key Advancements to Improve Photonic-Integrated Circuit Design

According to a SPIE’s report, researchers are making significant advancements to enhance the design of photonic-integrated circuits. Researchers are also working to resolve the large footprint issue of the all-optical photonic-integrated circuits.

Professor Vinod Menon from the City University of New York stated the large footprint issue has been resolved by utilizing plasmonic waveguides and a silicon-on-insulator method that were able to avoid the diffraction limit.

The Professor stated that another critical issue facing the optoelectronics’ experts is the  optical non-linearity of semiconductors. However, such weak optical non-linearity has been resolved by deploying quantum dots. Menon further added that quantum dots are ideal for optoelectronics because of its high quantum yield and diverse range of wavelengths. The quantum dots are also compatible with silicon technology and offer low-cost production option.
