A new evanescently coupled uni-traveling carrier photodiode （EC-UTC-PD） is designed, fabricated and characterized, which incorporates a multimode diluted waveguide structure and UTC active waveguide structure together. A high responsivity of 0.68 A/W at 1.55-μm without an anti-reflection coating, a...
