Titel
(2*2) digital optical switch realised by low cost polymer waveguide technology
Abstract
A novel (2*2) digital optical switch is reported involving thermo-optically induced adiabatic modal evolution. The device incorporates a symmetric X-crossing and a tapered overlapping area between electrodes and waveguides. Polarisation and wavelength insensitive switching is demonstrated at lambda =1.3 mu m and 1.55 mu m with a switching power of >or=45 mW and crosstalk values of <-25 dB.
