Abstract:
An on-chip mode converter-based silicon-germanium photoelectric detection apparatus comprises an insulating substrate, an optical coupler, an on-chip mode converter and a multi-mode silicon-germanium photoelectric detector. The optical coupler, the converter and the photoelectric detector are sequentially connected and all fixed on silicon wafers of the insulating substrate. An incident fundamental mode optical signal is transmitted to the optical coupler through a single-mode fiber, enters the converter via the optical coupled. The converter converts the fundamental mode optical signal into a multi-mode optical field and enters the photoelectric detector, which converts the multi-mode optical field into an electrical signal. Heavily germanium-doped region are located in areas with relatively weak distributed light intensity of the multi-mode optical field. The absorption loss of the heavily germanium-doped region and third through-holes on the optical field is dramatically reduced and the responsiveness of the apparatus can be improved effectively.

Claim (Index 5):
The photoelectric detection apparatus according to  claim 3 , wherein when the multi-mode optical field is in a first-order mode, there is only one heavily germanium-doped region on the interior top of the multi-mode germanium absorption waveguide, only one third through-hole is present between the germanium electrode and the heavily germanium-doped region, the multi-mode optical field has an optical field distribution of two circular optical spots, each circular optical spot has the strongest light intensity at its center, and the light intensity gradually attenuates from the center towards the periphery, the heavily germanium-doped region is located at an edge where outer contour lines of the two circular optical spots come into contact and is relatively far from the centers of the two circular optical spots, the position covered with the heavily germanium-doped region has a very weak light intensity, the absorption loss brought on the optical field by the heavily germanium-doped region and the third through-hole is dramatically reduced and the responsiveness of the silicon-germanium photoelectric detection apparatus can be improved effectively.
