In the lightwave signal transmission, the polarization state of the light is not maintained when a standard single-mode fibers are used. Hence, polarization independent EO devices are preferred to reduce the system complexity caused by an adaptive polarization controlling circuit. In lithium niobate substrates, there have been various investigations for the polarization-independent switches such as mode-evolution type digital switches [1], directional coupler switches with coincident coupling length for TE and TM modes [2], Mach-Zehnder (MZ) switches on x-cut, z-propagating orientation providing degenerated TE and TM modes [3], The switching voltages of these devices are 17 ~ 60 V. In this work, we propose a polarization-independent polymer waveguide modulator [4] which can be realized by integrating a polymeric polarization converters [5] in the middle of the MZ modulator. The optic-axis of the polarization converting waveguide is twisted 90 degree by poling it with specially designed electrodes.","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"27 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":"130286590","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}

Using polymer electro-optic materials, channel waveguide device can be comparative easily fabricated, but the main problem for polymer materials is their stability. On the other hand, organic single crystal has excellent stability, the disadvantage of them is the difficulty in processing which limited their application potential. Recently, channel waveguide has been fabricated by direct growth inside the hollow fiber, but those channel waveguides proved to be difficult to fabricate electrode besides the crystal [1]. By combining ideas of growth of crystal from hollow fibre and shear method [2], a new method able to fabricate raised-up channel waveguide of organic crystal was initiated. In this method, solution of organic molecule was introduced between two substrates, one of them has patterned lines on it. Due to the polar interaction between the substrate materials and molecules of the solution, Single crystal channel waveguides were grown along the patterned line on the substrate, the dimension and direction of the crystal materials were controlled by these patterned lines. Fig.1 illustrated the diagram of this method.","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"281 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":"124496290","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}

One of the most intriguing fullerene classes is the endohedral fullerene in which the spheroidal molecular structure is employed to encapsulate a small number of atoms (one to four) internal to the cage.1,2 Until recently, the difficult separation process of endohedral fullerenes had limited their availability to submilligram levels. Consequently, initial studies of these materials had primarily been restricted to electron paramagnetic resonance (EPR) and linear spectroscopy. EPR measurements demonstrated that, for the case of La@C82, the La atom transfers three electrons to the fullerene cage and resides in the +3 oxidation state.2 Metal-to-cage charge transfer appears to be a common feature of transition metal-containing endohedral metallofullerenes. Meanwhile, nonlinear optical studies of empty-cage C60 and C70 have shown that these materials possess both large third order susceptibilities χ(3)(−ω4;ω1,ω2,ω3)3 (~10-11 esu) and strong optical limiting behavior.4,5 We report here the first nonlinear optical measurements of an endohedral metallofullerene and find a dramatic enhancement in the third order nonlinear optical response. Degenerate four-wave mixing (DFWM) experiments on solutions of the endohedral metallofullerene Er2@C82 show that the metal-to-cage charge transfer provides a mechanism for increasing χ(3)(−ω4;ω1,ω2,ω3) by orders of magnitude relative to empty-cage fullerenes.","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"42 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":"115081254","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 taper provides a smooth transition between two waveguide sections with different mode sizes with minimum radiation loss. The tapered mode size transformer has become a standard approach for efficient fiber coupling with semiconductor lasers and amplifiers[1]. Various taper fabrication techniques are developed for semiconductor and LiNbO3 devices[2-5], but most of them are not applicable to polymer waveguides. Oxygen reactive ion etching is the primary method to etch a polymer film. For most polymer waveguides, the major part of fiber coupling loss is due to the mode size mismatch between the waveguide and fiber in the vertical direction, therefore a vertical taper is needed to reduce the fiber coupling loss. In this paper, a reactive ion etching (RIE) technique with a shadow mask is demonstrated. A similar technique has been reported for etching submicron tapers in InP with methane plasma[5]. Our approach can effectively create tapers several microns deep and a few millimeters long with oxygen plasma which is required for multilayer polymer waveguide structures.","PeriodicalId":378320,"journal":{"name":"Organic Thin Films for Photonics Applications","volume":"15 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":"116811820","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}
