Abstract:
1. An optical receiver module system used in a high-frequency optical communication system, the optical receiver module system comprising: a circuit board; a silicon substrate that is placed on and electrically connected to the circuit board and in which a V-shaped guide groove for arranging an optical fiber is formed; the optical fiber that is installed in the V-shaped guide groove and used as a path through which an optical signal is input; an oxidized porous silicon layer that is formed on the silicon substrate to prevent signal loss; a photo detector that is installed on the oxidized porous silicon layer, receives the optical signal input via the optical fiber, and converts the optical signal into a current signal; a current-voltage converter that is installed on the oxidized porous silicon layer and converts the current signal into a voltage signal; a signal oscillator that is installed on the oxidized porous silicon layer and generates a signal from the voltage signal; an optical receiver module that includes a signal transmission line for electrically connecting the photo detector, the current-voltage converter, and the signal oscillator; and an active circuit that is electrically connected to the circuit board and the optical receiver module; wherein the active circuit and the optical receiver module are electrically connected using a flip chip bonding method; and wherein the optical receiver module flip-chip-bonded to the active circuit is electrically connected to the circuit board using a flip chip bonding method.
