Abstract
An electro-optic polymer digital optical switch with rib waveguides is fabricated by using the reactive ion etching method. Polarisation-independent and wavelength-insensitive operation is demonstrated at wavelengths of 1.3 and 1.55 μm, for the first time in electro-optic polymer devices. The rib waveguides have been designed to achieve good guiding properties for both TE and TM polarisations by controlling the etching depth as well as its aspect ratio. The measured crosstalk is better than -16 dB and the extinction ratio of each output port is >16 dB
