A1 Xu, Dan-Xia A1 Janz, Siegfried K1 Comunicación por fibra óptica AB We use the concept of subwavelength grating(SWG) refractive-index-engineering topropose and experimentally demonstrate areduced size, slotted 2x2 MMI coupler. Wealso present an ultra-broadband 2x2 MMIcoupler which is based on SWG dispersion engineering.
