Low-cost packaging of VCSELs (vertical cavity surface emitting lasers) is essential for their applications in computers, communications and sensing. We discuss the fabrication of polymer-based microlenses on VCSEL arrays for beam shaping and efficient coupling with optical fibers. Drop–on-Demand Microfab Inkjet technique is employed to deposit SU8 lenses on GaAs substrates and on arrays of high-performance,...Continue Reading
We have developed conducting composite based on multi-walled carbon nanotubes and bisphehol. A novolak epoxy resin (SU8) for inkjet printing purposes. We could deposit regular conducting stripes and arrays of 150 mm spots on glass and on flexible polyethylene terephthalate (PET) films. The UV and temperature processed structures show very good adhesion and reasonably good...Continue Reading
Several recent detector technologies developed for particle physics applications are based on microfabricated structures. Detectors built with this approach generally exhibit the overall best performance in terms of spatial and time resolution. SU8–carbon nanotube composites have been produced to enhance the mechanical, electrical, and thermal properties of SU8 photoresists. Homogeneous composites materials have been obtained...Continue Reading
