Two-photon absorption photocurrent enhancement in bulk AlGaAs semiconductor microcavities
We report on two-photon absorption ~TPA! photocurrent in semiconductor microcavities. We experimentally show a substantial increase in the TPA photocurrent generated, at resonance, in a GaAlAs/GaAs microcavity designed for TPA operation at ;890 nm. An enhancement factor of ;12 000 of the photocurrent is obtained via the microcavity effect, which could have an important impact on the use of TPA ...
متن کاملCooperativity in biological systems
Living organisms can sense and respond to external and internal stimuli. Response isdemonstrated in many forms including modulation of gene expression profiles, motility,secretion, cell death, etc. Nevertheless, all forms share a basic property: they depend on sensingsmall changes in the concentration of an effector molecule or subtle conformational changes ina protein and invoking the appropri...
متن کاملBroadband and omnidirectional light harvesting enhancement of fluorescent SiC.
In the present work, antireflective sub-wavelength structures have been fabricated on fluorescent 6H-SiC to enhance the white light extraction efficiency by using the reactive-ion etching method. Broadband and omnidirectional antireflection characteristics show that 6H-SiC with antireflective sub-wavelength structures suppress the average surface reflection significantly from 20.5 % to 1.01 % o...
متن کاملEnhancement of Omnidirectional Reflection Bands in One-dimensional Photonic Crystals with Left-handed Materials
In this paper we show, theoretically, that total omnidirectional reflected frequency band is enlarged considerably by using onedimensional photonic crystal (PC) structure composed of alternate layers of ordinary material (OM) and left handed material (LHM). From the analysis it is found that the proposed structure has very wide range of omnidirectional total frequency bands for both polarizatio...
متن کاملEnhancement of the blue photoluminescence intensity for the porous silicon with HfO2 filling into microcavities
With HfO2 filled into the microcavities of the porous single-crystal silicon, the blue photoluminescence was greatly enhanced at room temperature. On one hand, HfO2 contributes to the light emission with the transitions of the defect levels for oxygen vacancy. On the other hand, the special filling-into-microcavities structure of HfO2 leads to the presence of ferroelectricity, which greatly enh...
