Title :

Manipulating Light at Wavelength-scale

Speaker :

Dr. Yinan ZHANG

PhD Graduate, School of Engineering and Applied Sciences

Harvard University, USA

Venue :

Room 215, William M. W. Mong Engineering Building, CUHK

Date :

Jan 16, 2013, Wednesday
2:00 PM - 3:00 PM

Abstract :

With the aid of state-of-the-art nano-fabrication technologies, light can be manipulated at a length scale on the order of, or even smaller than its wavelength. This talk will cover many topics in the area of nano-optics, including broadband anti-reflective coatings, customized on-chip optical filters, optical nanocavities, nano-lasers, microwave particle accelerators, etc.

Biography :

Dr. Yinan Zhang graduated in Electrical Engineering in 2007 from Tsinghua University, and received his doctorate degree in Electrical Engineering in 2012 from Harvard University. Dr. Zhang`s research focuses on developing nano-scale photonic devices on semiconductor chip to manipulate the emission and confinement of light. In particular, a large portion of his work is motivated by designing and fabricating ultra-high quality factor optical microcavities. These structures, capable of housing photons within a small length scale, greatly enhance the light-matter interactions, and enable a wide spectrum of fascinating applications, ranging from ultra-low threshold nanolasers, on-chip Terahertz source via optical enhanced nonlinearity, to particle accelerators at microwave frequencies.
