Spatial distribution of optical intensity of overgrown semi-polar (20-21) InGaN/GaN multiple quantum wells dominated by surface morphology

نویسندگان

چکیده

Polarized optical emission has been widely reported in semi-polar emitters as a result of the separation topmost valance bands. Simultaneously, exhibit isotropy spatial distribution intensity, which is attributed to influence surface morphology and configuration underlying templates for overgrowth. This paper reports that peanut-like pattern intensity observed (20-21) sample, where most emitted light located [11-20] direction. Compared with bottom air voids formed during overgrowth, it can be seen plays dominant role affecting overgrown sample. With different height deviations, could tuned from sideward rectangular-like pattern. These results will promote development polarized sources great potential application near-eye displays.

Strong Optical Filed Intensity Improvement Introducing InGaAsP Quantum Wells in InP Nanocavity

This paper presents the optical characteristics of a quantum well doped InP nanocavity.The resonance wavelength of the nanocavity and the optical field intensity is calculated before and after presence of the quantum wells. The resulting huge filed intensity of about 1.2×108 respect to the incident field is the effect of quantum wells placed in vicinity of center of nanocavity.

Resonant photodiffractive effect in semi - insulating multiple quantum wells

Received November 28, 1989; accepted April 10, 1990 We use semi-insulating multiple quantum wells to combine the holographic properties of the photorefractive effect with the large resonant optical nonlinearities of quantum-confined excitons. GaAs-AlGaAs multiplequantum-well structures are made semi-insulating by proton implantation. The implant damage produces defects that are available to tra...

Optical Physics of Quantum Wells

Quantum wells are thin layered semiconductor structures in which we can observe and control many quantum mechanical effects. They derive most of their special properties from the quantum confinement of charge carriers (electrons and "holes") in thin layers (e.g 40 atomic layers thick) of one semiconductor "well" material sandwiched between other semiconductor "barrier" layers. They can be made ...
