Benefits of technology

The present invention relates to an improved electronic device (ECD) component used in lightwave communication systems called Optically Wave Guide Elements (OWG). These components include various layers like dielectric films, metal plugs, and insulating materials. By creating these layers within specific regions where they interact well together, efficient charging/discharges may occur without causing problems such as increased power consumption due to reduced current flow caused by impurities from outside sources. This results in longer life span and less heat dissipation during operation compared to previous designs. Additionally, this design allows for effective application of AC bias fields while minimizing unwanted signals. Overall, this technology improves efficiency and reliability in Lightwaves Communications

Problems solved by technology

The technical problem addressed in this patented text relates to prevention of unwanted electrical effects from affects when light travels along certain paths due to variations in temperatures during use. This can cause issues like signal loss or distortions over time if there are no effective ways for these modifications.
