Photonic devices enabling light modulation and switching are of major importance for modern telecommunication. Silicon-based electro-optic modulators are intensively investigated because of their direct compatibility to CMOS fabrication processes. However, the performances of Si based modulators are intrinsically limited, in terms of data transmission rate and energy consumption. To overcome this...
A coupling technique for highly efficient coupling between SOI waveguides and standard single-mode fibers is experimentally demonstrated. The proposed coupling structure is CMOS compatible, polarization insensitive and aimed for being integrated with V-groove auto-alignment techniques.
