SiGe electro-absorption modulators for applications at 1550nm
A novel SixGe₁-x, electro-absorption modulator design is experimentally demonstrated. The device is waveguide integrated, butt-coupled into high index contrast Si/SiO2 waveguides. 0.75% Silicon concentration in the alloy is optimized for 1550nm applications. With its 400nm height, 600nm width, and …
