A novel terahertz waveguide: polymer tube
SPIE Proceedings, 2010A low-loss polymer tube which can trap a large part of mode power inside the air core is proposed and experimentally demonstrated for Terahertz wave guiding. Simulation results also show that an elliptical polymer tube can be used as a highly birefringent low-loss Terahertz waveguide.

Metallic waveguide mirrors in polymer film waveguides
Applied Physics B, 2001A technology for the fabrication of metallic waveguide mirrors is developed. Plane and curved waveguide mirrors, the latter acting in the same way as cylindrical lenses, are realized in benzocyclobutene (BCB) film waveguides. The waveguide mirror structure is dry-etched into the BCB film waveguide.

Modeling photobleached optical polymer waveguides
Applied Optics, 1995One of the most efficient ways to prepare nonlinear optical polymer channel waveguides is by photobleaching. To control the index profile precisely and to design and improve the performance of active electro-optical devices, modeling of the photobleaching process is important.

Optical waveguides structured with photoaligning polymers
Optics Letters, 2005We present a novel fast fabrication method for making optical waveguides by using a photoaligning and a liquid-crystal polymer. A difference in the refractive indices in the core and cladding regions is achieved by use of polarized UV light to align the polymer chains differently. A refractive-index difference of Deltan = 0.07 was achieved.

Efficient Coupling into Polymer Waveguides by Gratings
Applied Optics, 1997Investigations of highly efficient grating couplers for polymer slab and strip waveguides fabricated by electron-beam lithography are reported. A maximum input efficiency of 67% is achieved. The electron-beam direct-writing technique allows one to replicate the original gratings into polymer substrates by embossing.

Grating coupling to polymer optical waveguides
SPIE Proceedings, 1994We describe the production and optical characterization of planar dielectric waveguides of the organic polymers Poly-(alpha) -Methyl-Styrene and Poly-Phenyl-Acetylene. Single mode waveguides, at (lambda) equals 1.064 micrometers , were obtained by the use of the spin-coating technique.

Fabrication of polymer waveguides by a replication method
Applied Optics, 2006We have developed a soft-lithography method to replicate polymer waveguides. In this method, the waveguides are produced by a two-step molding process where a master mold is first formed on a negative-tone photoresist and subsequently transferred to a polydimethylsiloxane (PDMS) mold; a PDMS silicone rubber mold is then used as a stamp to transfer the ...
