Abstract
A novel digital thermo-optic switch based on a polymer waveguide has been demonstrated. The proposed switch consists of a conventional 1×2 digital optical switch and compact variable optical attenuators, with both elements integrated in series. The switches exhibit very low crosstalk values of -42 and -40 dB, and the switching power is ~170 mW at 1.5 μm
