Abstract :
Uni-traveling-carrier waveguide photodiodes (PDs) with variable optical confinement mode size transformers are demonstrated. For these waveguide PDs, the optical mode is large at the input for minimal front-end saturation. The mode transforms as the light propagates so that the absorption profile is optimized for both high-power and high-speed performance.
