Yu Yao

Yu’s research focuses on Quantum Cascade (QC) lasers, a type of semiconductor lasers based on intersubband transitions in coupled quantum well heterostructures. The laser emission wavelength can be flexibly tailored to cover the mid- to far-infrared wavelength region. She has enjoyed playing with hundreds of quantum wells to achieve novel QC laser designs with wide voltage tuning range, broad wavelength coverage as well as high power and efficiency.

Her research group are closely collaborated with many experts in spectroscopy, environmental sensing, medical diagnosis, etc. Their goal is to develop QC lasers that serve a wider range of applications.
