III-Nitride Integrated Micro-Cavity Photonic Devices

"The research proposed here is built on the promising results obtained in the Phase I project. During Phase I research, we have further improved blue micro-size light emitter output power efficiencies by optimizing the material qualities as well as devicestructures. Several integrated photonics devices have been fabricated and their operation under current injection has been achieved.The objective of this Phase II research is to develop technologies to fabricate integrated micro-photonic devices, including 1) develop bonding schemes to address micro-size light emitters individually in a high information content matrix array (up to 800x 800 pixels); 2) explore methods for the fabrication of full color microdisplays; 3) further improve the quality of III-nitride materials for micro-size light emitters and develop technology base for integrated III-nitride photonic devices, such asoptical circuits comprise microcavity disk/ring emitters and strongly confined waveguides on single chips.BENEFITS: III-nitride microdisplays can satisfy demands for hands-free and highly mobile applications in areas such as military, computing, entertainment, and head-mounted microdisplays for pilots, law enforcement officers, fire fighters, and medicaldoctors. In a few years, microdisplays may allow people to use computers and watch television without a real monitor, offering mobility, privacy, and fun. Thus there is market interest not only in military se
