    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.

    摘要： Provided is an optical module including a microstrip line, a traveling wave type optical device positioned in the end of the microstrip line, and at least one balanced open stub connected to the microstrip line for the impedance matching at a specific frequency such as 40 GHz and 60 GHz. For the fine tuning, laser trimming can be applied to the stub. A transition region is formed between the optical device and the microstrip line. A termination resistor is formed to face the microstrip line with the optical device therebetween. A bandwidth can be controlled at a specific frequency by adjusting a number of the stubs or a value of the termination resistor.

    摘要： Provided are an inductor, which is vertically formed, and an electronic device having the inductor, and more particularly, an inductor capable of minimizing loss of a surface area and accomplishing high efficiency impedance by vertically forming the inductor in a plurality of insulating layers, and an electronic device having the same. The inductor includes a plurality of conductive lines disposed in the insulating layers; and vias vertically formed in the insulating layers to electrically connect the plurality of conductive lines. When a board or an electronic device including an inductor proposed by the present invention is manufactured, the inductor can occupy a minimum area in the electronic device or board while providing high inductance. In particular, the surface area of the electronic device or board occupied by the inductor can be remarkably decreased to reduce manufacturing costs.
