SPIE Proceedings, 1994
Samples of PMMA (Poly-(Methyl-Meth-Acrylate)) in combination with various substrates have been modified by ionizing radiation in order generate regions of increased refractive index. These waveguiding structures were used to build passive devices such as Y-branches, couplers and Mach-Zehnder-interferometers. The refractive index and beam profil and the

Photoinduced diffraction in polymer waveguides
Applied Optics, 1993We report on techniques for measuring photoinduced diffraction in prism-coupled slab polymer waveguides. Diffraction effects resulting from photochromic gratings in slab waveguides of Disperse Red 1 dye in polymethylmethacrylate were studied. Optical damage in the form of diffractive mode conversion was observed when we coupled in light with a ...

Polymer waveguide star coupler
Applied Optics, 1982A polymer waveguide star coupler formed by the selective photopolymerization method is described. This polymer waveguide star coupler has low insertion loss independent of the core and cladding dimensions of the optical fiber. The six-port star coupler obtained, with input and output fiber arrays, had an insertion loss of 2.6 dB and a loss variation ...

Polymer and composite polymer slot waveguides
SPIE Proceedings, 2014A fully polymer slot Young interferometer operating at 633 nm wavelength was fabricated by using nanoimprint molding method. The phase response of the interference pattern was measured with several concentrations of glucose-water solutions, utilizing both TE and TM polarization states.

Polymeric waveguides doped with nonlinear organic materials have been fabricated by pre- and post-doping techniques. High quality, low-loss planar waveguides have been produced with doping concentrations in excess of 30% by weight. Selective doping has been used to define simple monomode channel waveguide structures. Fast acting nonlinear behaviour has

We report the first colinear single-mode polymer waveguide modulator that can be formed on any smooth surface—including semiconductors, conductors, and insula tors—regardless of its conductivity and refractive index. The tunability of polymer film allows us to shift the guiding layer from step index profile to graded-index profile.

Summaries of Papers Presented at the Lasers and Electro-Optics. CLEO '02. Technical Diges, 2003
Summary from only given. Polymer optical waveguide devices have attracted a lot of attention with regard to applications in the all-optical network, basically, because they have the potential of added optical functionality and because they may be producible at low cost. The combination of a large thermo-optic (TO) coefficient with low heat conductivity

Polymer waveguides and devices
Technical Digest. CLEO/Pacific Rim '99. Pacific Rim Conference on Lasers and Electro-Optics (Cat. No.99TH8464), 2003We have investigated two kinds of polymeric thermo-optical (TO) components, i.e. a 1×8 digital TO switch relying on adiabatic mode evolution and a TO tunable filter using a thermally-controlled arrayed-waveguide grating (AWG). Cross-linked waveguides are developed to have low insertion loss, polarization independence, moisture insensitivity, and thermo-
