Abstract
A novel digital thermo-optic switch based on a polymer waveguide has been d emonstrated. The proposed switch consists of a conventional 1x2 digital opt ical switch and compact variable optical attenuators. with both elements: i ntegrated in series. The switches exhibit very low crosstalk values of -42 and -40d8, and the switching power is similar to 170mW at 1.55 mum.
