Abstract :
The authors propose a novel waveguide photodiode structure that has an intentionally doped p-type region in the photoabsorption layer in order to make the operating voltage lower while keeping a high efficiency. The fabricated device has a high efficiency of 0.94 A/W and a 3dB bandwidth near 4 GHz at an operating voltage of 0 V. This waveguide photodiode is suitable for an optical hybrid module built with low-power ICs
