Compact Broadband Directional Couplers Using Subwavelength Gratings

Compact Broadband Directional Couplers Using Subwavelength Gratings

We experimentally demonstrate compact broadband directional couplers using subwavelength gratings for silicon-on-insulator wafers with silicon layers of 220 nm. The dispersion properties of the optical modes are engineered using subwavelength gratings, which allow broadband operation. Finite-differe...
