Porous silicon microcavities: synthesis, characterization, and application to photonic barcode devices
We have recently developed a new type of porous silicon we name as porous silicon colloids. They consist of almost perfect spherical silicon nanoparticles with a very smooth surface, able to scatter (and also trap) light very efficiently in a large-span frequency range. Porous silicon colloids have unique properties because of the following: (a) they behave as optical microcavities with a high ...
متن کاملStructural and optical properties of n- type porous silicon– effect of etching time
Porous silicon layers have been prepared from n-type silicon wafers of (100) orientation. SEM, FTIR and PL have been used to characterize the morphological and optical properties of porous silicon. The influence of varying etching time in the anodizing solution, on structural and optical properties of porous silicon has been investigated. It is observed that pore size increases with etching tim...
متن کاملEnhancement of the Spontaneous Emission Rates in All Porous Silicon Optical Microcavities
The emission properties of a porous silicon layer placed in an optical microcavity is investigated by photoluminescence and time resolved photoluminescence measurements. The microcavity is formed by an all porous silicon Fabry-Perot filter made by two distributed Bragg reflectors separated by a h or h/2 porous silicon layer. Our main findings are that the spontaneous emission spectrum is drasti...
متن کاملOn the Route towards Efficient Light Emitting Diodes Based on Porous Silicon
In this paper we present our recent progresses towards effkient light emitting diodes based on porous silicon. We will touch the two following topics: 1) All porous silicon microcavities. Through the formation of a planar optical cavity it is possible to vary the spontaneous emission rate of porous silicon films. We demonstrate this by showing luminescence, and time resolved luminescence measur...
متن کاملبررسی وابستگی میکروساختارهای سطحی سیلیکان متخلخل و خواص اپتیکی آن
We have studied the effect of increasing porosity and its microstructure surface variation on the optical and dielectric properties of porous silicon. It seems that porosity, as the surface roughness within the range of a few microns, shows quantum effect in the absorption and reflection process of porous silicon. Optical constants of porous silicon at normal incidence of light with wavelengt...
