摘要： Provided is an optical hybrid module in which an optical device, a filter, an amplifier and an antenna are hybrid-integrated, which includes: a silicon optical bench disposed on a substrate and having an optical fiber and an optical device; an amplifier disposed on the substrate and connected to the optical device disposed on the silicon optical bench to amplify a signal transmitted from the optical device; and an antenna disposed on the substrate to be connected to the amplifier and transmitting a signal amplified by the amplifier. Thus, a foot-print module may be embodied by disposing an antenna and a filter on a single- or multi-layer substrate and providing a bias required for the optical device and the amplifier through a solder ball. Also, due to the antenna and filter disposed on the substrate, an expensive connector is not needed, and thus a production costs can be reduced.

摘要： Provided is an optical module used in a communication system employing a radio over fiber (ROF) technology delivering a radio frequency (RF) signal through an optical fiber. The optical module includes: an optical device; a signal line for transporting a radio frequency (RF) signal input from an external circuit to the optical device; and a resistor separately disposed from the signal line and having one end connected with the optical device, wherein the input impedance seen from the signal line is matched by the resistor. A bias voltage supplied to operate the optical device is applied through an inductor connected to the signal line between the optical device and a filter. Here, the filter formed by a pattern of the signal line prevents the bias voltage from being supplied to the external circuit. In order to amplify the RF signal input from the external circuit, an amplifier may be connected between the external circuit and the filter.
