A 1×4 Polymeric Digital Optical Switch Basedon the Thermo-Optic Effect
-
Abstract
We present a 1×4 Y-branch digital optical switch in which S-bend variable optical attenuators are integrated.The S-bend waveguides,which are always introduced to connect the switch and the standard fiber array,are made use of and designed as variable optical attenuators.A compact device with low crosstalk and larger branching-angle is obtained.The device is fabricated on the thermo-optic polymer materials,and the performance of the device is measured.With an applied driving power of less than 200mW,the device has a low crosstalk of less than -35dB at a wavelength of 155μm -
