A Microprism Array for Large-Scale, Wide-Band Interconnection of Optoelectronic Systems

In contrast to any existing means of interconnection for a large-scale, high-speed optoelectronic system, Physical Optics Corporation POC proposes fabricating and using a microprism -100 um in size, array MPA as a wide-band coupler for two-dimensional and three-dimensional system integration. The flexibility of MPAs angles allows implementation of the MPA to any point to point interconnects. Realizing that the major bottle neck of hologram-based interconnection is the intrinsic limitation of coupling bandwidth -10 um, we demonstrated a microprism coupler MPA with larger than 200 um bandwidth from free space to optical data bus ODB. For example, LED-based transmission from a single-mode guide to a multimode fiber can be solved only by using the MPA. Unlike the conventional prism which has a dimension of -mm to -cm, the MPA has miniscule dimensions. An MPA with -100 Jim in size as demonstrated. The proposed MPA is immune from electromagnetic interference EMI. Furthermore, the cost of the microprism is less than S1 a piece in mass production, significantly less than holograms. In Phase 1, fabrication of the MPA will be upgraded followed by a demonstration of large-scale board-to-board MAP-based 3-D interconnection.
