AI Technical Summary

Benefits of technology

This patented innovation allows an optoeletronic module (EOM) used in coherence optics communications to have both light split function and 90° phase shifting capabilities. It achieves these benefits by having very wide optically active regions at different angles around its surface or inside which are designed specifically for specific types of signals called polarization modes. These modules also include certain features like amplification stages and signal processing circuits, making them ideal for use in long distance transmission systems where there may be changes over time caused by temperature fluctuations. Overall, they offer technical advantages such as compactness, reduced energy usage, lower costs, higher reliability, ease of integration into electronic devices, etc., leading to improved performance and functionality within various applications involving telecommunicational equipment.

Problems solved by technology

Technologies aim towards improving integration between electronic componentry and optically active media within optoeletronics modules called CMOS Intermediate Passage Components (CIC), resulting in improved performance capabilities over existing technologies. One approach involves embedding these components into hybrid fiber coaxial cable(HFC)-based photonic crystal fibre (PCF) converger module designs without compromising electromagnetic conversion properties. Another option includes incorporate integrated circuits onto chip packages instead of separate parts, but there may also exist methods involving modifying the physical dimensions of the passives themselves during manufacture.
