Abstract:
A photodiode (PD) device that monolithically integrates a PD element with a waveguide element is disclosed. The PD device includes a conducting layer with a first region and a second region next to the first region, where the PD element exists in the first region, while, the waveguide element exists in the second region and optically couples with the PD element. The waveguide element includes a core layer and a cladding layer on the conducting layer, which forms an optical confinement structure. The PD element includes an absorption layer on the conducting layer and a p-type cladding layer on the absorption layer, which form another optical confinement structure. The absorption layer has a length at least 12 μm measured from the interface against the core layer.

Claim (Index 1):
A photodiode device, comprising:\n a substrate providing a conducting layer doped with n-type impurities, the conducting layer having a first region and a second region next to the first region; a waveguide element provided on the first region of the conducting layer, the waveguide element including:\n a core layer provided on the conducting layer, and \n a cladding layer provided on the core layer; and \n a photodiode element provided on the second region of the conducting layer, the photodiode element being optically coupled with the waveguide element and including:\n an absorption layer that is provided on the conducting layer and has a bandgap wavelength longer than 1612 nm, the absorption layer abutting against the core layer in the waveguide element, and \n a p-type cladding layer that is provided on the absorption layer and doped with p-type impurities, \n wherein the absorption layer in the photodiode element has a length at least 12 \u03bcm along an optical axis thereof measured from an interface against the core layer in the waveguide element.
