This work presents the experimental measurement of the extraction lengths of individual guided modes of embedded photonic-crystal (PhC) light-emitting diodes (LEDs), which corroborates its superior guided light extraction compared to surface PhC LEDs. Whil ...
Thin-film InGaN photonic crystal (PhC) light-emitting diodes (LEDs) with a total semiconductor thickness of either 800 nm or 3.45 mu m were fabricated and characterized. Increased directional radiance relative to Lambertian emission was observed for both c ...
This work explores the impact of cavity thickness, photonic crystal etch depth, and quantum well placement on the extraction efficiency and emission directionality of thin-film InGaN photonic crystal light-emitting diodes (LEDs). ...
The enhancement of the extraction efficiency in light emitting diodes (LEDs) through the use of photonic crystals (PhCs) requires a structure design that optimizes the interaction of the guided modes with the PhCs. The main optimization parameters are rela ...
Record fundamental mode output power of 8mW at 0 degrees C and 6.5mW at room temperature is achieved with wafer-fused VCSELs incorporating regrown tunnel junction and emitting at the 1550nm waveband. (C) 2009 Optical Society of America ...

For the past couple of decades the desire to add more complexity to a computer chip, while simultaneously reducing the cost per bit, has been accommodated by down-scaling. This approach has been extremely successful in the past, but like all good things it ...
Novel light-emitting devices and micro-optical-circuit elements will rely upon understanding and control of light-matter interaction at the nanoscale. Recent advances in nanofabrication and micro-processing make it possible to develop integrable solid-stat ...
This PhD thesis describes the experimental study of wurtzite III-nitride semiconductors grown on non-polar crystal orientations, namely (1120) a- and (1010) m-planes. Hindered by poor material quality, they were not as extensively investigated as the polar ...
Novel 1310 nm and 1550 nm optically pumped VECSELs based on wafer fused InAlGaAs/InPAlGaAs/GaAs gain mirrors demonstrate high CW fundamental mode continuous wave output in excess of 2 W at room temperature. ...

Limitations in extraction efficiency of gallium nitride (GaN) photonic crystal (PhC) light emitting diodes (LEDs) are addressed by implementing an LED design using both two-dimensional PhCs in-plane and index guiding layers (IGLs) in the vertical direction ...
