Glycidylmethacrylate (GMA) was polymerized by 2,2'-azobisbutyronitrile in tetrahydrofuran at 60/spl deg/C. for 1 hour. Poly-GMA dissolved in dimethylformamide containing nonlinear optical chromophore, disperse red 1 (DR1) or disperse orange 3 (DO3), and 4,4'-diaminodiphenylmethane as cross-linker was spin-coated on pyrex glass substrates. The films were dried and heat-treated for cross-linking at 100/spl deg/C for 1 hour. The chromophore molecule was fixed in the crosslinked polymer network. To form a periodical structure the films were patterned by photolithography and reactive ion etching using O/sub 2/ plasma. Poly-GMA without cross-linker containing the chromophore was spin-coated to fill the etched grating grooves. The films were poled at 100/spl deg/C for 1 hour. The films were periodically poled because the cross-linked part was not poled due to the raised transition temperature.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

The most effective way to expand network capacity is to increase the number of WDM channels, and a persistent demand has emerged for a large-scale multiplexer/demultiplexer with a narrow channel spacing that can support the maximum number of channels. We have found a way to extend the channel number beyond 1,000 by using a tandem configuration. This consists of a one l /spl times/ N primary filter and a number of secondary 1 /spl times/ N 10 GHz-spaced arrayed waveguide gratings (AWGs). The primary filter has flat-top passbands whose channel spacing is 1 THz. We connect one secondary AWG to each output port through an optical fiber.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

The Q-factor of the received signal, for the worst case path, was higher than 10 dB for all the channels. In particular, we show that the dynamic add/drop functionality in the network does not affect the system performance when gain controlled amplifiers are used.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

Lightwave communication systems use fiber-optics to transport signals between nodes, and will use optical layer networking to optimally manage signal paths under normal and disrupted network conditions. New micromachine devices (MEMS) are poised to significantly impact the advancement of both networking and transmission. The deployment of MEMS based optical cross connects, such as Lucent's LambdaRouter, allow network flexibility in the optical domain and open the path to optical layer networking. Optical wavelength add-drop switches are a key component in the emerging ultra long haul (>2000km) transmission systems and will expand the optical layer traffic management. The conversion of the optical layer from one of static links to dynamic reconfigurable network will require that the optical transmission system characteristics are reconfigurable. Demonstrations of MEMS variable attenuators, optical spectrum equalizers and dispersion compensators show the potential for robust signal transport in such networks.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.

Effect of plasma etching on sidewall roughness was also studied by fabricating different width waveguides and measuring their loss. The understanding of surface roughness evolution was used to explain the roughness effects observed in sidewalls and strategies to minimize the same have been developed. Fluorinated polyimides were used as candidate materials for this study. Roughness evolution on the top surface of the polyimide films was studied by exposing the film to an oxygen plasma under different conditions. After each run, the amount of material etched was measured and a non-contact AFM scan of the surface was obtained.","PeriodicalId":18008,"journal":{"name":"LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat.
