Optical module and optical transmitting apparatus installing a number of optical modules

An optical transmitter apparatus that generates a multiplexed optical beam, comprising:

• the number of optical modules each including,
• an electrically insulating carrier that provides a ground pattern and a bias pad on a top surface thereof, the bias pad being electrically isolated from the ground pattern thereby forming a parasitic capacitor against the ground pattern,
• a semiconductor element mounted on the ground pattern, the semiconductor element generating a modulated optical beam supplied with a bias current thereto,
• a capacitor mounted on the ground pattern, and
• at least two bonding wires among a first bonding wire connecting the semiconductor element with the bias pad, a second bonding wire connecting the bias pad with the capacitor, and an additional bonding wire connecting the capacitor with the semiconductor element,
• wherein the bias current is supplied to the semiconductor element from the capacitor through the at least two bonding wires;
• and
• an optical multiplexing system that multiplexes the modulated optical beams generated in the optical modules into the multiplexed optical beam.
