ABSTRACT:
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.
