Semiconducting polymer waveguides for end-fired ultra-fast optical amplifiers.

A method to fabricate conjugated polymer waveguides with well defined edge facets is demonstrated. The utility of the approach is explored for application as end-fired ultrafast optical amplifiers based on poly(9,9'-dioctylfluorene-co-benzothiadiazole). An internal gain of 19 dB was achieved on a 760 microm long waveguide at 565 nm wavelength. This fabrication procedure may be applied to a wide...

Flow boundary conditions for chain-end adsorbing polymer blends.

Using the phenol-terminated polycarbonate blend as an example, we demonstrate that the hydrodynamic boundary conditions for a flow of an adsorbing polymer melt are extremely sensitive to the structure of the epitaxial layer. Under shear, the adsorbed parts (chain ends) of the polymer melt move along the equipotential lines of the surface potential whereas the adsorbed additives serve as the sur...

Electronic stability of silicon front-end hybrids

Stability of front-ends hybrids is often not well understood. Multiple feedback loops are mostly the source of instabilities. The power distribution and ground system are the major common part of the circuit and play a dominant role in the oscillation. Adding only decoupling capacitors does not work, since power distribution foils of a Kapton hybrid have a very low Ohmic impedance. In addition ...
