Abstract
A new type of Y-junction optical switch structure based on refractive- index-controllable waveguides is investigated. Switching operation is observed when polarity of the reverse bias applied between the two arm s of the Y-branch is alternated. A crosstalk of less than - 12 dB is a chieved with a transition length of less than 400 mum at a 1.06-mum wa velength. An optical switch is realizable with this structure that has small size, large optical bandwidth, and high speed.
