Bottom-metal-printed thermo-optic waveguide switches based on low-loss fluorinated polycarbonate materials.

In this work, thermo-optic (TO) waveguide switches are designed and fabricated based on the bottom-metal-printed technique. Low-loss fluorinated polycarbonate (AF-Z-PC MA) and polymethyl methacrylate (PMMA) are used as core and cladding materials, respectively. The thermal stability and optical absorption characteristics of AF-Z-PC MA are analyzed.

Metal-printing polymer waveguide thermo-optic switches compatible with 650 and 532 nm visible signal wavelengths for plastic optical fiber systems.

In this work, thermo-optic (TO) waveguide switches for 650 and 532 nm visible wavelengths are designed and fabricated by the metal-printing technique based on poly (methyl methacrylate-glycidyl methacrylate) [P(MMA-GMA)] material. The optical characteristics and thermal stability of the P(MMA-GMA) material are analyzed. Optical transmission modes in the core waveguide for different visible wavelengths are simulated, and the thermal field distribution from the self-heating electrode structure is calculated, respectively.

Fluorinated photopolymer cascaded MMI-based integrated optical waveguide switching matrix with encoding functions.

In this work, thermo-optic tunable 4 × 4 cascaded multimode interference based integrated optical waveguide switching matrices are designed and fabricated using photopolymer lightwave circuits. The materials of the waveguide core and cladding are fluorinated epoxy-terminated copolycarbonate and polymethylmethacrylate, respectively. The driving power that controls matrices for binary encoding of different optical switching states are simulated and analyzed.

Fluorinated photopolymer waveguide thermo-optic switches with loss-compensation function based on erbium-containing cladding structure.

In this work, a novel polymer thermo-optic switch with loss compensation function is successfully designed and fabricated by direct UV-writing technology. The waveguide core and cladding layer material of the switch are based on the low-loss fluorinated photopolymer and erbium-containing gain copolymer. The absorption loss characteristics and thermal stabilities of the core and cladding materials are studied.
