On the development of a low-cost lithographic interferometer
… source - a bulky and expensive metal-vapor laser - is replaced by a newly available, low-cost blue laser diode. Additionally, the passive alignment of a lens tube is utilized to simplify the construction of a spatial filter. The resulting custom-built interference lithography tool is able to …

Materializing Light: Real-time, Handheld Fabrication of Programmable Structural Color
… wavelengths. Within the device, red, green, and blue laser diodes go through an optical prism, combining light and producing mixed color outputs on the film. Additionally, we introduce a resin-based process to adhere and integrate the structurally-colored film with flexible and rigid objects and …

Processing and characterization of contacts on MBE-grown gallium nitride
… is a good candidate for applications such as blue laser diodes and power devices due to its wide bandgap. One of the main challenges related to this compound is the growth of high quality crystals. If crystals with high level of purity are grown, the carrier concentration is therefore low, and …

Depletion, quantum jumps, and temperature measurements of ⁸⁸Sr⁺ ions in a linear Paul Trap
… describes the design and construction of two laser systems to probe the 674nm transition of ⁸⁸Sr⁺ ions in a linear Paul trap. The first laser system made use of a molecular transition in Iodine to stabilize the length of a Fabry-Perot cavity for laser locking. After constructing this laser, we …

Commercialization of group III nitrides-on-silicon technologies
… the InGaN/GaN white light emitting diode and the blue laser diode, as well as the AIGaN/GaN high electron mobility transistor, each with its own unique requirements for the technology and the implementation. It was recommended that start-up firms interested in commercializing GaN-on- Si technology …
