Abstract :
This paper presents a bend-bend coupler for an ultra-small microring resonator based on Si nanowires in order to reduce the mode-conversion loss at the coupling region. And relatively large amplitude coupling coefficient and low coupling loss are achievable due to the long coupling length of the bend-bend coupler.
