Vertical-cavity surface-emitting lasers with lateral carrier confinement
Introduction: Optics is a viable solution to address the limitations of copper-based electronics in short-distance interconnects [1]. In these compact systems, devices must meet the stringent requirements imposed by the power budget and the thermal restriction. Recently, VCSELs have received considerable interest for board and chip level interconnects owing to their small footprints, ease of fa...
متن کاملOrthant Spanning Simplexes with Minimal Volume
A geometry problem is to find an (n−1)-dimensional simplex in Rn of minimal volume with vertices on the positive coordinate axes, and constrained to pass through a given point A in the first orthant. In this paper, it is shown that the optimal simplex is identified by the only positive root of a (2n−1)-degree polynomial pn(t). The roots of pn(t) cannot be expressed using radicals when the coord...
متن کاملNanoscale volume confinement and fluorescence enhancement with double nanohole aperture
Diffraction ultimately limits the fluorescence collected from a single molecule, and sets an upper limit to the maximum concentration to isolate a single molecule in the detection volume. To overcome these limitations, we introduce here the use of a double nanohole structure with 25 nm gap, and report enhanced detection of single fluorescent molecules in concentrated solutions exceeding 20 micr...
متن کاملA Minimal Volume Ellipsoid around a Simplex
This paper presents a complete proof of the fact 1 that the ellipsoid with minimal volume containing the regular simplex is a sphere (lemma 4). It is shown also that the proof can be used to build and compute easily minimal volume ellipsoids around irregular simplex (Theorem 1). Some consequences are presented. The first two lemmas deal with the wellknown (see [2],[3]) Steiner and Swarz symmetr...
متن کاملDiffraction from oxide confinement apertures in vertical-cavity lasers
Direct measurement of scattered fields from oxide confinement apertures in vertical-cavity lasers is presented. Diffraction fringes associated with each transverse lasing mode are detected in the far field from devices with varying oxide aperture dimensions and with quantum efficiencies as high as 48%. The diffracted pattern symmetries match the rectangular symmetry of the oxide apertures prese...
