An optical sensing apparatus is provided. The optical sensing apparatus including: a substrate including a first material; an absorption region including a second material different from the first material, the absorption region configured to receive an optical signal and generate photo-carriers in response to receiving the optical signal; an amplification region formed in the substrate configured to collect at least a portion of the photo-carriers from the absorption region and to amplify the portion of the photo-carriers carriers; a buried-dopant region formed in the substrate and separated from the absorption region, wherein the buried-dopant region is configured to collect at least a portion of the amplified portion of the photo-carriers from the amplification region; and a buffer layer formed between the buried-dopant region and the absorption region, wherein the buffer layer is intrinsic and has a thickness not less than 150 nm.
