Abstract:
1. An optical module comprising: a stem; a thermo-electric cooler (TEC) on the stem; a first sub-mount on the TEC; an optical element on the first sub-mount; a plurality of electrode lead wirings inserted from an outside to an inside of the stem and disposed adjacent to the TEC and the optical element; a second sub-mount between the electrode lead wirings and the optical element; radio frequency (RF) transmission lines on the second sub-mount; a plurality of bonding wires connecting the RF transmission lines and the optical element, the plurality of bonding wires connecting the RF transmission lines and the electrode lead wires; and an impedance matching unit disposed around the RF transmission lines and the electrode lead wirings, the impedance matching unit controlling impedances of the RF transmission lines and the electrode lead wirings.
