Abstract :
Grating couplers for efficient coupling between silicon sandwiched slot waveguides and standard singlemode fibres are demonstrated. Coupling efficiency up to 20% is experimentally measured for TM polarisation and a wavelength of 1550% nm. A 20% nm 1% dB bandwidth is also obtained. Higher coupling efficiency is expected for particular designs according to simulation results.
