Pathways to ultra-high efficiency in III-nitride light-emitters for solid-state lighting are explored. This includes exploiting stimulation emission in laser diodes, and also the high optical gain and spontaneous emission rates in quantum dot active

Technologies for artificial lighting have made tremendous progress over the centuries. At this point in time, there is virtually no question that solid-state lighting (SSL) will eventually displace its predecessor technologies. A remaining question,

The workshop participants enthusiastically concluded that the time is ripe for new fundamental science to beget a revolution in lighting technology. SSL sources based on organic and inorganic materials have reached a level of efficiency where it is p

We have investigated methods of chemical preparation and thermal treatments of InSb substrates to produce InSb surfaces suitable for subsequent molecular beam epitaxy. Etching in a solution of lactic acid: HNO3:HCl was shown to produce an oxide surfa

The technology of crystal growth has advanced enormously during the past two decades; among those advances, the development and refinement of molecular beam epitaxy (MBE) has been among the most important. Crystals grown by MBE are more precisely con

Artificial light has long been a significant factor contributing to the quality and productivity of human life. As a consequence, we are willing to use huge amounts of energy to produce it. Solid-state lighting (SSL) is an emerging technology that pr

Using a new technique called resonant periodic absorption, we have achieved high-optical gain in InGaAs/GaAs heterojunction phototransistors (HPTs) for wavelengths at which GaAs substrates are transparent(>925 nm). These devices are promising for opt

Optically-pumped long-wavelength vertical-cavity surface-emitting lasers (VCSELs) have been fabricated exhibiting more than 2mW over 20–70°C, and 1.25mW at 85°C. Small-signal modulation measurements on the VCSEL at 20°C indicate a 3dB bandwidth
