A T-slot waveguide optical interconnect is proposed that can be realised on a photonic integrated circuit with sub – wavelength silicon slot waveguides and can redirect optical power to optical devices placed perpendicular to each other. In the proposed configuration, all critical parameters of high index waveguide and low index slot of all three arms are optimised. A power splitting efficiency of 54% is achieved which is almost independent of operating International Telegraph Union (ITU) grid C Band wavelengths. By judicious modification in T-slot waveguide configuration, power splitting efficiency is enhanced up to 73%.
