Compact Dual-Mode Adiabatic 3-dB Coupler for the 2-µm Waveband on Silicon Using Fast Quasi-Adiabatic Dynamics

We propose a 2 × 2 dual-mode adiabatic 3-dB coupler for the 2-μm waveband on silicon. The proposed coupler is designed based on fast quasi-adiabatic dynamics. The optimized taper shape is effective to reduce the device length. The length of the coupling region with the optimize...
