Abstract :
This paper describes in details design, fabrication and test of a new compact ARROW optical coupler placed at the border of an IC device. This coupler uses vertical directional coupling between a rib ARROW waveguide and a strip silicon submicronic waveguide assisted by a grating. Modelings show that a 75% coupling efficiency can be obtained while measurements were up to 50%.
