    • An optical module includes a stem; a first lead pin and a second lead pin for receiving differential signals, the first and second lead pins penetrating the stem; a mount block fixed to the stem; a laser diode having a pair of electrodes; a submount mounted on the mount block and having an interdigital capacitor, and a plurality of electrode patterns on a surfaces on the submount; and a first wire and a second wire electrically connecting the submount to the first and second lead pins, respectively. The laser diode is mounted on one of the electrode patterns on the submount and connected to another one of the electrode patterns on the submount by a third wire such that the laser diode and the interdigital capacitor form an electrical circuit. The interdigital capacitor has a capacitance selected to reduce signal reflection at a selected frequency.
