  • Abstract
    Analysis of light field distribution within a dual-absorption RCE p-i-n photodetector has been performed. A formula for the field distribution inside the cavity is derived. This formula is derived from the continuity equations, and employed to evaluate the frequency response of the dual-absorption RCE photodetector. This photodetector has been optimized for high-speed applications. The optimized structure shows a 3dB bandwidth of 20 GB with intrinsic absorption region to be 400nm, as well as effective illumination area and peak quantum efficiency to be 900 μm2 and 92%, respectively.
