ABSTRACT:
An optical transmitter/receiver unit having an optical connector with an optical device array block and a multi channel optical fiber block is presented. The optical device array block includes at least one optical device for converting an electric signal to an optical signal or for converting an optical signal to an electrical signal. The optical devices is mounted on a silicon optical bench having a series of grooves for inserting, attaching and aligning each optical device. The optical device array block can be optically coupled to a multi channel optical fiber block that includes at least one optical fiber for transmitting an optical signal, the optical fiber being mounted in V-shaped grooves on a silicon V block. The V-shaped grooves on the V-block and the mounting grooves on the silicon optical bench allow for accurate alignment of each optical fiber with corresponding optical devices. In the optical device array block, a surface of metal lead connected to an electrode of optical device is formed widely so as to enable ball bonding of wires between the electrodes of the optical devices and the metal leads.
