conference on lasers and electro optics | 2017

A compact and low-loss GeSn electroabsorption modulator using vertical multimode interference for mid-infrared Ge-on-Si platform

Minami Akie; Takanori Sato; Masakazu Arai; Takeshi Fujisawa; Kunimasa Saitoh

A novel GeSn electroabsorption modulator using vertical multimode interference is proposed for mid-infrared photonics. The size of the proposed device is 1/3 with lower loss and larger extinction ratio compared with conventional structure.
