Through molecular engineering, solventless UV curable guiding and cladding materials with appropriate optical and mechanical properties have been synthesized for waveguide applications in the visible and near-infrared wavelength regions. The solventless feature of these materials made them possible to fabricate thick waveguides in single process. Novel planarization technique have been developed to overcome the problems of surface waviness of the PCBs. Multimode (>75 microns) waveguides have been fabricated to distribute control signals to multiple transmit/receive (T/R) modules on large-array radar antennas. To date, waveguide structures with straight, curved, Y-split and tap geometries have been designed and fabricated successfully on PCBs; good light intensity outputs from Y-split and multiple-tap buses were obtained. This paper will discuss the materials and optical circuit fabrication of the waveguide structures and the results of laboratory tests using the optical buses for control signal distribution to T/R modules.","PeriodicalId":246676,"journal":{"name":"Organic Thin Films for Photonic Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125774497","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}

These polymer films are formed by spin coating using standard semiconductor equipment and manufacturing processes. The polymer films are amorphous as spun and cured, so the polarizable chromophores are randomly arranged, and therefore no second-order electro-optic effects occur. Electric-field poling has been used to make a variety of EO polymer devices2,3,4,5, but the process is not well understood. In electric field poling the EO polymer is heated above its glass transition temperature Tg, a voltage is applied by electrodes to align the nonlinear chromophore molecules in the direction of the field, and the material is cooled back to room temperature under the influence of the electric field. While the voltage is applied to the cladding/core/cladding stack of films, the electric field divides in some manner so that a portion of the applied voltage appears across each of the film layers, as illustrated in Figure 1.","PeriodicalId":246676,"journal":{"name":"Organic Thin Films for Photonic Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131702681","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}

These environments vary according to process and ultimate application, but many require longterm thermal stability to 125 °C and short excursions to 250 °C or higher.1 Our efforts with EO polymers have been directed toward thermally stable waveguide devices2 and polyimide-based guest-host material systems.3 We recently demonstrated a proof-of-principle all-polyimide triple stack Mach-Zehnder based on DCM (4-(dicyanomethylene)-2-methyl-6-(p-dimethylaminostyryl)-4H-pyran) as the active chromophore in the core waveguide layer.4 The structure of DCM is shown in Figure 1(a). Advantages of DCM include low absorbance at device wavelengths, photobleachability, compatibility with polyimides and their polyamic acid precursors, and commercial ability at high purity. DCM is less than optimum in its thermal characteristics, however. It out-diffuses when heated above 220 °C for significant periods of time and it plasticizes the host material. This plasticization depresses the glass transition temperature Tg, and is detrimental to long-term stability of the poled state.","PeriodicalId":246676,"journal":{"name":"Organic Thin Films for Photonic Applications","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130935650","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}
