AlGaN/AlN distributed bragg reflectors for deep ultraviolet wavelengths
Distributed Bragg reflectors with up to 21 periods consisting of AlN and Al 0.58 Ga 0.42 N layers were grown by metalorganic chemical vapor deposition. A periodic structure and good interface quality was verified by both transmission electron microscopy and X-ray diffraction, and was shown to be dependent on the composition of the underlying AlGaN base layer. Reflectivities of 49.8% at 285 nm a...
متن کاملHigh-Quality Crystal Growth and Characteristics of AlGaN-Based Solar-Blind Distributed Bragg Reflectors with a Tri-layer Period Structure
To realize AlGaN-based solar-blind ultraviolet distributed Bragg reflectors (DBRs), a novel tri-layer AlGaN/AlInN/AlInGaN periodical structure that differs from the traditional periodically alternating layers of high- and low-refractive-index materials was proposed and grown on an Al0.5Ga0.5N template via metal-organic chemical vapour deposition. Because of the intentional design of the AlInGaN...
متن کاملIntegrated Photonics based on Planar Holographic Bragg Reflectors
Integrated holographics is a novel photonics technology made possible by recent advances in semiconductor manufacturing technology and planar waveguide fabrication. The technology’s corner stone, the holographic Bragg reflector (HBR), is a slab-waveguide based, nanoscale, refractive-index structure that merges, for the first time, powerful features of holography, such as single-element spectral...
متن کاملCharacteristics of Plasmonic Bragg Reflectors with Graphene-Based Silicon Grating
We propose a plasmonic Bragg reflector (PBR) composed of a single-layer graphene-based silicon grating and numerically study its performance. An external voltage gating has been applied to graphene to tune its optical conductivity. It is demonstrated that SPP modes on graphene exhibit a stopband around the Bragg wavelengths. By introducing a nano-cavity into the PBR, a defect resonance mode is ...
متن کاملReflectance Mapping of Semiconductor Distributed Bragg Reflectors
We describe the design, construction and performance evaluation of a spectrally resolved reflectance mapping setup. The setup is capable of mapping a full 2 inch diameter semiconductor wafer, with a best spatial resolution of 50μm. The operating wavelength range is from 0.35μm to 1.05μm with spectral resolution of ~1nm. We have used this setup for reflectance mapping studies on distributed Brag...
