Solution-processable, mechanically-flexible lasers
… feedback resonators are chosen due to their planar fabrication and their potential for lower threshold than other cavities in the case of solution-processed lasers. Two types of gain materials are used: organic semiconductors and colloidal quantum dots. Encapsulation schemes compatible with …

Nanostructured Origami (TM) : stress-engineering of nanopatterned membranes to produce three-dimensional structures
Microdevice fabrication is done on the surface of polished flat semiconductor substrates with a series of material depositions, etches and lithography steps. These processes are inherently planar and well suited for the fabrication of billions of micrometer-thick transistors over 300 mm diameter …

Novel rare-earth-doped planar waveguide lasers
The planar guided-wave geometry is compatible with a wide range of materials, waveguide architectures and fabrication techniques. This thesis reports a series of studies of rare-earth-doped planar waveguide lasers, exploiting and extending the diverse range of possibilities that can be applied to …

Selective Deposition of Copper Traces onto Additively Manufactured All-Aromatic Polyimides via Laser Induced Graphene to Enable Conformal Printed Electronics
… deposition of complex copper traces. The fabrication of an Archimedes spiral on a hemispherical substrate via Cu-LIG is completed to demonstrate the ability to use the process to fabricate conformal conductive traces. An LED circuit is fabricated on a face-center cubic AM-PI lattice which …

Fundamental Components for Lamina Emergent Mechanisms
… lamina emergent mechanisms are fabricated out of planar materials (the lamina) but their motion is out of that plane (emergent). Lamina emergent mechanisms can provide benefits that include reduced manufacturing costs and minimal volume when in the planar state. The compact initial state of LEMs …

Fabrication of Hollow Optical Waveguides on Planar Substrates
<p>This dissertation presents the fabrication of hollow optical waveguides integrated on planar substrates. Similar in principle to Bragg waveguides and other photonic crystal waveguides, the antiresonant reflecting optical waveguide (ARROW) is used to guide light in hollow cores filled with …
