Because of the small and nondispersive dielectric constants of polymer materials, over 100 GHz modulation can be achieved with a simple integrated microstrip line circuit [3]. However, in order for these polymer modulators to be usable in commercial fiber-optic data links, several other device performance figures have to be improved. In addition to the often-discussed thermal stability issue, the halfwave voltage, optical insertion loss, optical power handling capability, and bias control stability are all of vital importance to the commercial application of polymer E-O modulators. Future polymer photonic devices must have a balanced overall performance, with a much lower cost, broader bandwidth, and competitive thermal, photochemical and bias control stability. We have reported our fabrication and testing of integrated Mach-Zehnder modulators using a double-end-crosslinked NLO polymer LD-3 [4-5]. The LD-3 based modulators have exhibited higher thermal stability, photochemical stability and low optical insertion loss compared to the E-O modulators based on the PUR-DR19 polymer [2]. However, because the LD-3 polymer has a lower E-O coefficient r33, and the corona poling schedule was not optimized, our LD-3 modulators exhibited a higher halfwave voltage which is not acceptable in most applications. In this paper, we report our new device fabrication technique that effectively reduced the halfwave voltage by one-half using an optical push-pull structure in M-Z modulators.","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115543611","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main interest of such doped or functionalized systems is due to their dichroic and birefringent properties when they are illuminated by a polarized light. Such an effect is a consequence of the reversible “trans↔cis” photoisomerisation with respect to the N=N double bond which causes a redistribution in the orientation of photochromic entities. In this respect, Dumont et al.1 have already reported the basis of a simple three-level theoretical model in order to explain the reorientation mechanisms of the azo molecules within a photoisomerisation cycle. Hereafter we thus report the results of a dynamical study of the photoisomerisation-induced reorientation of DR1-azo-dye in a polymer matrix (PMMA) by in-situ time dependent Visible and polarisation modulation FTIR spectroscopy measurements. The last part concerns the generation of high-efficiency diffraction patterns obtained by holographic way.","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129996082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Remarkable progress have been made in development of electroactive CT materials such as organic metals, conducting polymers, and organic photoconductors (OPCs). Among them, OPCs are widely used for electrophotographic applications. Besides photoconductive properties, it has been elucidated experimentally and theoretically that organic inter- and intracharge transfer compounds exhibit large nonlinear optical (NLO) responses. We have investigated the third-order NLO properties of polymeric CT materials based on poly-n-vinylcarbazole (PVK) complexed with 2,4,7-trinitrofluorenone (TNF) in terms of the complex composition.1 The values of χ(3) (-3ω; ω,ω,ω) increased linearly with the content of CT complex in the film. Recently large refractive index changes have been demonstrated in organic photorefractive polymers based on PVK/TNF systems.2 Carbazole compounds play a significant part in electroactive and NLO applications. In order to utilize the unique properties of polymer backbone, acceptor-substituted carbazole moiety was incorporated into the main chain through either 3,6- or 3,9-linkage. In this paper we discuss the multifunctional photoresponses in various carbazole main-chain polymers with shoulder-to-shoulder, head-to-tail, and hyper-branched arrangements as shown in Figure 1.","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133470793","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
