Starting from the early days of Maxwell’s equations, Einstein’s A and B coefficients on the spontaneous and stimulated emissions, then quantum mechanics,  important historical events such as the inventions of transistors, masers, and lasers, and semiconductor lasers will be presented.  We will review stories of a few scientists making these revolutionary contributions.  We will discuss the concepts of confinement of photons or optical waveguides, confinement of electrons based on semiconductor quantum wells and quantum dots, and the interaction of light with matter, which leads to the field of photonics and optoelectronics.  
Recent research trend toward nanophotonics including our work on nanoplasmonic lasers using surface plasmon and quantum dots will be presented.  The smallest semiconductor laser requires an optical cavity, which is a half wavelength in all three directions, which is called the diffraction limit.  To reduce the active volume of a laser small than the diffraction limit, surface plamonics using metal plasmas has been researched.  The idea of a nano-bowtie antenna in the optical wavelength coupled to semiconductor quantum dots as an optical gain medium will be discussed.  Challenges on how to make an ultra-small or nanolaser will be addressed.  
Finally, some lessons learned from history to be shared with young scientists conclude the talk.

Shun Lien Chuang received his B.S. degree from National Taiwan University in 1976; and M.S., E.E., and Ph. D. degrees from MIT in 1980, 1981, and 1983, respectively. He is the Robert MacClinchie Distinguished Professor in the Department of Electrical and Computer Engineering, University of Illinois at Urbana-Champaign.  His research interest is on semiconductor nanophotonic devices. He is the author of Physics of Photonic Devices (second edition 2009), Wiley, New York.  He has published more than 300 papers in leading technical journals and conferences.  
        He is a Fellow of APS, IEEE, and OSA. He received Engineering Excellence Award from OSA in 2004, IEEE/LEOS Distinguished Lecturer Award in 2004 to 2006, William Streifer Scientific Achievement Award from IEEE/LEOS in 2007, and the Humboldt Research Award for Senior U.S. Scientists in 2009.
