Photonic Integrated Circuit for Optical Communication and Biosensing
Abstract:
With the rapid advancement of information technology, the capacity of optical communication has surged dramatically, making conventional optical communication techniques inadequate to meet current application demands. Photonic integrated circuits (PICs), leveraging advanced micro/nano-fabrication technologies, integrate various functional optical devices onto a single chip to construct sophisticated photonic chips. Compared with traditional optical systems, PICs offer advantages such as smaller size, higher integration density, and richer functionality, while also demonstrating superior performance. Furthermore, optoelectronic integrated chips effectively combine the mature electronic technology with the benefits of photonic, such as low power consumption and high-speed parallel processing. As the integration level of PICs continues to increase, on-chip power compensation has become a bottleneck hindering their further development. To address this issue, rare-earth-ion-doped on-chip amplifiers have emerged as a key research focus. This talk provides an overview of erbium-doped optical waveguide amplifiers for photonic chip applications and also touches upon certain aspects of photonic chip-based biosensor technologies.
