Flat panel displays play an essential role in our everyday life. Promising new comers like blue phase liquid crystals have demonstrated the possibility to reproduce images at 240Hz frame rate without any alignment layer. Organic light emitting diodes (OLEDs) displays which lead to thinner screen and improved color rendering are now implemented in some commercially devices. Micro inorganic light emitting diodes (µ-ILEDs) could also be the technology for true flexible displays with improved lifetime. For telecommunications of the future operating at frequency higher than 110GHz, electro-optic polymers with improved thermal stability remain very promising for making Mach-Zehnder interferometers with driving voltage less than 1V at the telecom wavelength of 1.55µm. Amplification of telecommunication signals required for a variety of loss compensated components is currently achieved using well-established planar integrated optics technology based on erbium doped glass or silica-on silicon. The strong demand for increased bandwidth has generated a lot of interest for Er complexes which are compatible with polymers processing to achieve low cost components.
