Welcome to the Yu Group at USC

With ever-increasing demand for processing both classical and quantum information, it is clear that Moore’s law is nearing its end within the next few years. The next technological revolution will be to fully unlock the power of light (low loss, large bandwidth and extreme precision) by nanoscale photonic technology, enabling light-matter interactions at ultralow optical powers and massive integration of optical and electronic devices on a single chip.

Our lab will lead efforts in integrated nonlinear photonics for classical and quantum applications. We aim to advance the fundamental understanding of nonlinear sciences at nanoscale, as well as realize next-generation optoelectronic circuits which could sit on our finger tips and solve real-life problems in classical and non-classical optical communication, computing, sensing, ranging and metrology.
