ABSACSide chain polyrrers containing hyperpolarizable noieties as the periant groups have been applied as optically ncrilinear traterials to produce polyxreric integrat1 electro-optical devices . Phase nixiulators, intisity nixiulators (1ch-Zebzx1er interferaiters) aixi optical 2*2 sce switches ( 2*2 directixa1 nixie couplers) have been uncle . Driving voltages as 1ci as 2 Volts (V ) have been obtain1 for a 24 nm active 1gth çkmse ncdulator; 4.4 Volts (V ) for a 14 inn active 1angthch-Zebrx1er interferarter, ath 9 Volts for a 14 nm active length directionI node ccupler. Intisity nixiulation ratios of about -23 dB atti -17 dB have been derived for the intensity nixiulator atd nixie ccxipling switch, respectively. The device properties , theni.l arxi electrical stabilities , etc. will be discussed. The results obtained shcw that optically txnlinear polyiTers are attractive caixlidates for the realizaticzi of polyireric integrated electro-optical devices. In additicn, several passive veguiding devices have beai nnde.
ThTflO1UTIONOptically ncilinear polynrs, incllL4ing solid solutious of hyperpolarizable trolecules in polynEr hosts ath hyperpolarizable side groups covaltly attached to a polyner backixtie, have been used for neking optically ncrilinear devices for several years.Hxver, solid solutions suffer fran the limited anuint of active species that can be dissolved in the polyner aixi fran the related terx1icy for segregation, limiting severely both the ngnittx1e atd the SPIE Vol. 1337 Nonlinear Optical Properties of Organic Materials 111(1990) / 215 Downloaded From: http://proceedings.spiedigitallibrary.org/ on 06/26/2016 Terms of Use: http://spiedigitallibrary.org/ss/TermsOfUse.aspx
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
