Photonic devices

LED-based lighting is the most efficient source of white light ever created. Despite this success there are many challenges that remain to advance solid-state lighting to ultra-efficiency.  While at Sandia, Prof. Wierer and J. Tsao pioneered the idea of using lasers for SSL. Our group continues researching other advances, including III-nitride photonic integrated circuits, efficiency droop mitigation, micro-LEDs quantum dots, nano-scale and photonic crystal emitters, and higher efficiency designs at green-red wavelengths.  These emitters have applications in lighting, displays, and quantum computing.

III-nitride materials, growth, and physics

More broadly, our group is interested in III-nitride materials, growth, and physics.  III-nitride semiconductors are versatile and possess attractive properties such as —interband and intersubband transitions from the ultra-violet to infrared, tunable spontaneous and piezoelectric polarization, a facile ability to form nanostructures, high critical electric fields, thermal oxidation of AlInN, and stabilities to extremely high temperatures. Because of these properties, III-nitrides are an almost ideal platform for novel semiconductor device research.
