Abstract:
A functional optical device applicable to a coherent optical communication system as a front end device is disclosed. The functional optical device includes a pair of light-receiving elements of a type of waveguide photodiode (PD), a pair of signal pads, a pair of ground pads, a bias pad, and a substrate that monolithically integrates those elements thereon. The light-receiving elements generate a photocurrent complementary to each other in respective anodes thereof; while, receive biases through the bias pad common to the light-receiving elements. Those pads are disposed along an edge of the substrate such that the signal pads put the bias pads therebetween, and the ground pads put the signal pads and the bias pad therebetween.

Claim (Index 12):
An optical apparatus implemented in a coherent communication system, the optical apparatus optically receive signal light and local light, and outputs an electrical signal, the optical apparatus comprising:\n a functional optical device claimed in  claim 1 ; an amplifier unit outputting the electrical signal, the amplifier unit providing a pair of ground pads connected with the ground pads in the functional optical device, a pair of signal pads connected with the signal pads in the functional optical device, and a bias pad connected in the functional optical device; and bonding wires each connecting the ground pads, the signal pads, and the bias pads between the functional optical device and the amplifier unit, wherein the bonding wire connecting the bias pads between the functional optical device and the amplifier unit is put between the bonding wires connecting the signals pads, and the bonding wires connecting the signal pads between the functional optical device and the amplifier unit and the bonding wire connecting the bias pads between the functional optical device and the amplifier unit are put between the bonding wires connecting the ground pads between the functional optical device and the amplifier unit.
