An integrated circuit for feedback control & compensation of an organic LED display
… A solution has been proposed which uses organic photo-detectors and optical feedback to control the desired luminosity on a per-pixel basis. This thesis demonstrates the design and fabrication of an integrated silicon control chip and an organic pixel/imaging array, which together form a stable, …

Integrated Inp Photonic Switches
Photonic switches are becoming key components in advanced optical networks because of the large variety of applications that they can perform. One of the key advantages of photonic switches is that they redirect or convert light without having to make any optical to electronic conversions and vice …
