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 1):
A functional optical device implemented in a coherent communication system, comprising:\n a coupling unit that generates a pair of optical signals complementary to each other by preforming interference between signal light and local light; a pair of optical waveguides that carry the optical signals, a pair of light-receiving elements of a type of waveguide photodiode (PD) that provides an anode and a cathode, the light-receiving elements generating a pair of photocurrents complementary to each other based on the optical signals, and a pair of signal pads each connected with the anodes of the light-receiving elements, a pair of ground pads, and a bias pad connected with the respective cathodes of the light-receiving elements; and a substrate that monolithically integrates the optical waveguides, the light-receiving elements, the signal pads, the ground pads, and the bias pad thereon, wherein the signal pads put the bias pad therebetween, and the ground pads put the signal pads and the bias pad therebetween.
