摘要	This invention relates to a novel stack-integration package of a light emitter and a photodetector in a high speed, full duplex optical transceiver for fiber communications. The structure is comprised of a photodetector chip, having an isolated micromachined cavity on the chip surface, and a light emitter chip, stacked on the bottom surface inside that cavity, so that a stack-integrated embodiment of light detector and emitter capable of performing full duplex optical communication is resulted. Said cavity surface in the photodetector is coated with reflective metal to prevent direct optical crosstalk from the emitter to the photodetector. Said light emitter means either LED (light emitting diode) or LD (laser diode). The present invention is further characterized by having a transparent encapsulation over the stack-integrated embodiment with a specific surface contour that minimizes the Fresnel reflection at the encapsulation-air interface and its associated crosstalk aftereffect. Such packaging structure is particularly suitable as a component for the purpose of single-core, full-duplex optical fiber communications.
其他摘要	本发明涉及一种用于光纤通信的高速全双工光收发器中的光发射器和光电探测器的新型叠层集成封装。该结构包括光电探测器芯片，在芯片表面上具有隔离的微机械腔，以及堆叠在该腔内的底表面上的光发射器芯片，使得光探测器和发射器的堆叠集成实施例能够执行完整的产生双工光通信。光电探测器中的所述腔表面涂有反射金属，以防止从发射器到光电探测器的直接光学串扰。所述光发射器指LED（发光二极管）或LD（激光二极管）。本发明的特征还在于，在叠层集成实施例上具有透明封装，其具有特定的表面轮廓，其最小化封装 - 空气界面处的菲涅耳反射及其相关的串扰后效。这种封装结构特别适合作为用于单芯全双工光纤通信的部件。
