Replicated polymer optical waveguides
SPIE Proceedings, 2003A novel replication technology for fabricating polymer optical waveguides has been developed and named as SPICA (Stacked Polymer optical IC/Advanced). SPICA is superior to current semiconductor fabrication technology because it satisfies the needs of low-cost and high-volume manufacturing.

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-

Soviet Journal of Quantum Electronics, 1982
A review is given of the optical, chemical, physical, and technological properties of polymer fiber waveguides. These waveguides are classified in accordance with their structure, properties of the materials used to make them, and fabrication methods. The main operating characteristics of the waveguides are given: the absorption and scattering in the ...

Polymer Waveguide Birefringence Modulators
IEEE Photonics Technology Letters, 2012Birefringence modulators for controlling the phase retardation between transverse electric (TE) and transverse magnetic (TM) polarizations are demonstrated based on polymeric waveguides. Highly birefringent polymer material is incorporated to increase the polarization dependence of the thermo-optic (TO) effect.

Polymer waveguide based biosensor
SPIE Proceedings, 2008Planar-integrated optical biosensors based on the interferometric evanescent wave sensing principle facilitate highly sensitive label-free detection of biomolecules. In this work, we present a novel polymer waveguide device concept that allows for cost effective fabrication of disposable sensor chips by utilizing injection moulding and spin-coating ...

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.

Embossed polymer waveguide devices
Conference on Lasers and Electro-Optics Europe, 1994Recently there has been renewed interest in moulding and embossing of polymers as potentially cheap methods of mass producing passive waveguide devices.1,2 Manufacturing components with good optical performance by these methods requires careful control of the fabrication process and the use of materials with optimised properties.

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.

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.
