Subwavelength structure
Webthat such a structure supports a bound mode in a wide frequency range. Within this range this mode has a wave vector larger than all radiation modes in air and silica, as well as all propagating modes in the air–silver–silica thin film structure. The cutoff fre-quency of this mode is 0.005 2 c/w, where c is the speed of light in free space. WebAn on-chip silicon dual-mode multiplexer (MUX) is proposed via a subwavelength grating (SWG)-based directional coupler and a mode blocker. The proposed mode MUX is optimized by utilizing the three-dimensional full-vectorial finite-difference time-domain-based band structure and propagation calculations.
