摘要:The thermal droop (reduction of the optical power when the temperature is increased) is a phenomenon that stronglylimits the efficiency of InGaN-based light-emitting diodes. In this paper we analyze the role of Shockley-Read-Hall(SRH) recombination and of the electron blocking la...

摘要:One- and two-dimensional MEMS scanning mirrors for resonant or quasi-stationary beam deflection are primarily known as tiny micromirror devices with aperture sizes up to a few Millimeters and usually address low power applications in high volume markets, e.g. laser beam scanning ...

摘要:With a use of electro-optic modulator based comb generator, ultra-wideband optical comb is stably and flexibly synthesized from a continuous-wave light. Larger modulation depth at a higher repetition rate would proportionally enhance bandwidth of the generated comb. Practically, ...

摘要:This paper deals with an experimental non-destructive technique for the measurement of polarization behavior of integrated optical waveguides. It is based on a high resolution polarimeter associated to an ellipsometric-type calibration which allows determining the full state of p...

摘要:Monolithic integration of nonreciprocal optical devices on semiconductor substrates has been a long-sought goal of the photonics community. One promising route to achieve this goal is to deposit high quality magneto-optical (MO) oxide thin films directly on a semiconductor substr...

摘要:Photonic crystals manipulate photons in a manner analogous to solid-state crystals, and are composed of a dielectric material with a periodic refractive index distribution. In particular, two-dimensional photonic-crystal slabs with high index contrasts (semiconductor/air) ar...

摘要:This work is devoted to a new family of highly emissive white phosphors for solid-state lighting (SSL) applications. The phosphors, based on yttrium aluminoborates (g-YAB) compositions, were prepared from solutions by the polymeric precursor (PP) method (modified Pechini process)...

摘要:Detecting the UV part of the spectrum is fundamental for a wide range of applications where ZnMgO has the potential to play a central role. The shortest achievable wavelength is a function of the Mg content in the films, which in turn is dependent on the growth technique. Moreove...

摘要:This work is novel in that it explains the modeling and simulation of a thulium-doped fiber amplifier (TDFA) in a reconfigurable wavelength division multiplexing (WDM) system operating at 2 μm. We use the optical gain-clamping technique in order to control gain amplification a...
