Metallic waveguide mirrors in polymer film waveguides

Applied Physics B, 2001
A 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.

Single-mode rib polymer waveguides and electro-optic polymer waveguide switches

Optics and Lasers in Engineering, 2002
Abstract Mode-matching and effective index methods are used to analyze single-mode operation of optical rib polymer waveguides. Their single-mode waveguiding conditions are determined. Single-mode rib waveguides fabricated from guest–host polyetherketone are presented. The estimated propagation loss of straight rib-waveguides is 0.7 dB/cm at 1.55 μm.

Replicated polymer optical waveguides

SPIE Proceedings, 2003
A 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), 2003
We 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-

Polymer fiber waveguides

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, 2012
Birefringence 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, 2008
Planar-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, 2010
A 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, 1994
Recently 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.
