Flexible Distributed Bragg Reflectors from Nanocolumnar Templates
Recently, another alternative route to the use of purely polymeric structures to attain fl exible Bragg mirrors, and in which enhanced dielectric contrast is achieved, has been successfully demonstrated. [ 22,23 ] Such method takes advantage of multilayers possessing an open porous and interconnected network, which arises as a result of piling up layers of nanoparticles, to infi ltrate a polyme...
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...
متن کاملFabrication of large-area patterned porous silicon distributed Bragg reflectors.
A process to fabricate porous silicon Bragg reflectors patterned on a micrometer lateral scale over wafer areas of several square centimeters is described. This process is based on a new type of projection system involving a megavolt accelerator and a quadrupole lens system to project a uniform distribution of MeV ions over a wafer surface, which is coated with a multilevel mask. In conjunction...
متن کاملAlGaN/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 کاملCharacterization of waveguide loss using distributed Bragg reflectors
We propose and demonstrate a method to characterize waveguide loss using the spectral response of combinations of distributed Bragg reflectors. The method is independent of coupling efficiency and waveguide dispersion and does not require the introduction of bending loss into the device.
