Professor Milton Feng demonstrated a tiny, fast device along with postdoctoral researcher Fei Tan, graduate students Mong-Kai Wu and Michael Liu, and Nick Holonyak Jr., who is an emeritus professor. The device is a new laser technology developed at the University of Illinois that transmits error-free data over fiber optic networks at a blazing fast 40 gigabits per second – the fastest in the United States. The team published its results in the journal IEEE Photonics Technology Letters.
