Abstract:

The increased complexity of electronic circuits and reduced component sizes has resulted in large numbers of InputOutput IO interconnections for each module layer. However, the number of electrical interconnects that can be placed at module layer edges is limited. In addition, electrical interconnects are sensitive to external electromagnetic interference and interchannel electrical cross talk. In response to these issues, Physical Optics Corporation POC evaluated a new optical IO pin and pin grid array concept for two dimensional interlayer interconnects and system IO. POCs concept is based on commercially available fibers, optical lenses, vertical cavity surface emitting lasers, and highly sensitive photodiode arrays. The advantages of the optical pin concept include high data rate IO GHz speeds, low loss, low signal propagation delay, high immunity to Electromagnetic Interference EMI, low cross talk at high speeds, high pin count 200cm2 to 2500cm2, and low cost.
