Micro-Raman scattering measurements were used to study the phonon modes and to analyze the local variation of composition and strain in the micron range of AlxGayIn1-x-yAs materials grown in the re
Many integrated photonics applications require miniaturized on-chip sources over a wide wavelength range, such as coherent optical communication and spectroscopy.
In this work, we demonstrate for the first time a narrow-linewidth III-V-on-Si laser with more than 110 nm wavelength tuning range realized using micro-transfer printing (uTP) technology.
Semiconductor layers of InGaAsP and InGaAs grown in narrow gaps between SiO sub 2 stripes, which are separated by several microns, are important building blocks in modern optoelectronics.
Unusual physical properties in alloy systems are anticipated when the spatial confinement of atoms, say in a particle of angstrom dimensions (nanoparticle), is coupled to the equilibrium or nonequi
For the full potential of presently available optical fibers to be realized, care will have to be taken to minimize any perturbations that affect the fiber's transmission.
Two types of optical fibers appear to be promising for wideband communications, the monomode step-index fiber and a multimode fiber with parabolic (or nearly parabolic) refractive index distributio
Microchemical and Special Methods of Analysis in Communication Research By BEVERLY L. CLARKE and H. W.
This article addresses the question, 'Of what use will microcomputers be in the operation of libraries?' The answer is seen to rest in the application of traditional systems design techniques to c
The connectivity threshold (predicted by constraint theory 1 to occur at x=0.20) is found experimentally at x+0.23 (2) in GexSe1-x glasses 2 and at x=0.20 (1) in (Si, Ge)x Te1-x glasses.
