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 10):
The functional optical device according to  claim 1 ,\n wherein the functional optical device includes a pair of units each including the optical waveguides, the light-receiving elements, the signal pads, the ground pads, and the bias pad, wherein the coupling unit generates two pairs of the optical signals, one of the pairs of the optical signals being provided to the one of the units, another of the pairs of the optical signals being provided to another units, and wherein each of the units further includes a groove extending along the one of the optical waveguides disposed closer to the other units, respectively.
