Abstract

Three new design waveguides for adiabatic directional full couplers are studied. We theoretically and numerically show that the performance of new full couplers is improved. Whe the length of the coupler is 4mm (the minimum local beat length is 2mm) at 1.57μm wavelength, the crosstalk is smaller than -35dB. For the length of the coupler is 4mm, the crosstalk is smaller than -20dB in the 1.5μm ~ 1.7μm range. For the length of the couplers is 7mm, we find that the crosstalk is smaller than -35dB in the 1.5μm ~ 1.7μm range. The same as the requirement of the maximum crosstalk, the corresponding wavelength is between 1.42μm to 1.7μm when the lenght of the couplers is 12mm.
