We analyze the waveguide properties of microstructure optical fibers consisting of a silica core surrounded by a single ring of large air holes.

We analyze the waveguide properties of microstructure optical fibers consisting of a silica core surrounded by a single ring of large air holes.

This paper reviews recent experimental and theoretical studies of InGaAs strained layer quantum wells and superlattices grown on InP and GaAs substrates.

We describe optical properties of ultra-small quantum wires and quantum wells structures based on In sub (x) Ga sub (1-x) As/InP.

We report the growth and characterization of multiple layers of self-organized InAs quantum dots emitting near 1.3microns.

Some of the most exciting prospects for future opto-electronic applications are those emerging from technologies based on GaAs.

We have studies the optical absorptions of a series of point defects in SiO sub 2 by means of time-dependent Density Funciotnla response theory, TD-DFT.

We explore theoretically the possibility of obtaining efficient light emission from Si-Ge semiconductor nano-onions.

Photoluminescence spectra of GaAsSb.GaAs quantum wells grown by molecular beam epitaxy exhibit strong blue shifts of the emission peak with increasing excitation intensity, indicating a type II ban

We report both experimental and theoretical studies of the optical properties in KCI of a defect-associated In center whose sole previously identified optical transition was a strong band peaking a
