Reflectance 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 کاملFlexible 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 کاملCompositional grading in distributed Bragg reflectors, using discrete alloys, in vertical-cavity surface-emitting lasers
We present experimental results on a technique for alloy composition grading within distributed Bragg reflectors (DBRs) for use in vertical-cavity, surface-emitting lasers (VCSELs). This technique, implemented using molecular beam epitaxy (MBE), employs multiple group-III sources, with different fluxes, to realize a set of AlxGa1 xAs compositions without changing cell temperatures. By varying t...
متن کاملSilicon Substrates With Buried Distributed Bragg Reflectors for Resonant Cavity-Enhanced Optoelectronics
We report on a commercially reproducible silicon wafer with a high-reflectance buried distributed Bragg reflector (DBR). The substrate consists of a two-period DBR fabricated using a double silicon-on-insulator (SOI) process. The buried DBR provides a 90% reflecting surface. We have fabricated resonant cavity-enhanced Si photodetectors with 40% quantum efficiency at 860 nm and a full-width at h...
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...
