HAS TECHNOLOGICAL DEVELOPMENT SO FAR ALLOWED TO INCREASE THE UNDERSTANDING? DO THE PROCESSING OF ELECTRONIC DEVICES DO NOT INCREASE COSTS AND CONSUMPTION THANKS TO THE PROGRESSIVE DEVELOPMENT OF SILICON TECHNOLOGY AND A MARKET FOR ALWAYS PI PRODUCTS? THIS HAS HELPED TO OFFSET THE VERY HIGH COSTS OF TECHNOLOGY. IS IT NOT POSSIBLE TO FURTHER CHANGE PERFORMANCE? PI? RELY ON ELECTRONIC TECHNOLOGY ONLY BECAUSE OF THE CONSTRAINTS IMPOSED ON THE INTERFACES OF THE/OR THE CHARACTERISTICS OF THE MATERIAL AND THE EQUALISATION TECHNIQUES USED, AND REQUIRES THE SEARCH FOR SOLUTIONS BASED ON OPTICAL INTERCONNECTIONS AND PHOTONICS COMPONENT PARTS THAT ARE INTEGRATED WITH THE USE OF THE PHOTONICS SILICON TECHNOLOGY. ARE YOU? ARE SOME OF BOTH PASSIVE AND PASSIVE COMPONENTS AVAILABLE IN SILICON PHOTONICS AVAILABLE IN SILICON PHOTONICS, WHICH ARE A NUMBER OF LIMITATIONS, WHICH? NEED TO RESOLVE, IN ORDER TO ASSURE ITS FULL AUTHORISATION AND ITS WIDESPREAD USE.
