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 λ=1.3 μm and 1.55 μm with a switching power of ⩾45 mW and crosstalk values of <-25 dB
