| Abstract(in English) | We proposed a new design principle for a photodiode structure that has a depleted InGaAs absorption layer combined with a neutral p-type InGaAs absorption layer. When the total thickness of the absorption layer is constant, the thickness ratio between those two layers has an optimum value to minimize the carrier delay time and yield the highest bandwidth. This optimal structure simultaneously provides the highest efficiency for a required bandwidth. A fabricated photodiode with a 0.8-μm InGaAs absorption layer yielded a responsivity of 0.98 A/W and a bandwidth of 50GHz, demonstrating a superior efficiency/bandwidth tradeoff over a conventional pin photodiode. In addition, the fabricated device exhibited better linearity and 5-10dB smaller distortion component (IP_3) indicating its feasibility for analog applications. |
