This paper gives a brief overview on the recent advances on photonic devices based on carbon materials such as: graphene waveguides or photonic devices on paper or plastic substrates in analogy with carbon based electronic devices. The four building block for electronics are the electrons as carrier's information's vectors, the generators, the cables and the transistors. In the same way, photonics or plasmonics will achieve in the future the capability to do same operations done actually in electronics by using photons or plasmons. Following the same steps as in electronics, new technologies were developed in photonics in order to produce photonic integrated circuits (PIC) first on silicon and more recently on plastic or paper substrates. If we analyze the present achievements we can notice that the already equivalent building blocks for photonics on paper substrates are already done: laser on paper substrate (as signal generators), optical and plasmonic waveguides (as information transport cables), optical and plasmonic transistors, photodetectors based on carbon materials etc. In this paper we present by analogy with electronics the recent advancements on paper and carbon based photonics devices. As for electronics, some of the most important advantages of these materials are that they are mechanically flexible, lightweight, cheap and environmentally friendly. • A briefly overview on technologies and materials for photonics on paper substrates. • State of art on perovskite materials for solar cells, LED and lasers. • State of art on plasmonic modulators based on graphene. • New perspectives for the development of future integrated photonic devices.

This paper discusses the use of etalons fabricated from prepared glass slides to quantify the dimensional stability of two adhesive materials in damp environments. This technique facilitated the screening of adhesives for a kinematically demanding application. In addition to describing the etalon technique, additional data are provided on the performance of the device with the selected adhesives. One of the adhesives is simply identified as a cationic cured adhesive, while the other adhesive was Loctite 3615. A range of adhesive bond gaps from 50 to 500 μm was examined for the adhesive that showed the least displacement resulting from environmental aging. The results of this testing were applied to a kinematically sensitive device for verification of the adhesives use in this geometry. [ABSTRACT FROM AUTHOR]
