Ying-Jay Yang (楊英杰) was born in I-Lan, Taiwan, in 1952. He received the B.S. degree in electrical engineering from National Taiwan University in 1974, the M.S. degree and the Ph.D. degree in electrical engineering from North Carolina State University, in 1982 and 1987 respectively. During his Ph.D. work he invented the first quantum well Transverse Junction Stripe (TJS) lasers and also the first CW operation strained-layer TJS lasers. From 1987 to 1989 he was an engineer at Hewlett Packard, working on the development of 1.3 um InGaAsP LEDs for FDDI. From 1989 to 1993 he joined Lockheed Palo Alto Research Laboratory as a research scientist.
He worked on the vertical-cavity surface emitting lasers (SELs), invented the first single transverse mode SELs and the first optoelectronic integration circuits (OEICs) with a SEL and a FET. Since February 1993 he jointed the Department of Electrical Engineer, National Taiwan University as an associate professor. His current research areas are semiconductor materials, and devices including lasers, modulators, quantum devices, and OEICs.
