Alfred Yi Cho (Chinese: 卓以和; pinyin: Zhuó Yǐhé; born July 10, 1937) is a Chinese-American electrical engineer, inventor, and optical engineer. He is the Adjunct Vice President of Semiconductor Research at Alcatel-Lucent's Bell Labs. He is known as the "father of molecular beam epitaxy"; a technique he developed at that facility in the late 1960s. He is also the co-inventor, with Federico Capasso of quantum cascade lasers at Bell Labs in 1994.
Cho was elected a member of the National Academy of Engineering in (1985) for his pioneering development of a molecular beam epitaxy technique, leading to unique semiconductor layer device structures.
