Thermal strain effects on the excitonic states in GaAs/AlxGa1−xAs multiple quantum wells
Temperature-dependent absorption experiments have been performed to investigate the effect of thermal strain in GaAs/AlxGa1−xAs multiple quantum wells clad by thick AlGaAs layers. A temperature-...

Nanocrystalline Nd12Fe80B6Nb1Ga1 melt-spun ribbon with textured surface
In Nd-Fe-B melt-spun ribbon, Ga addition is found to be effective for the orientation of c axis of 2-14-1 grains normal to the ribbon plane even at high wheel surface velocity. A Nd12Fe80B6Nb1Ga1 melt...

In this paper we discuss a novel material which has nearly ideal properties at optical frequencies. It combines the low dissipation of a dielectric with the reflectivity of a metal. This material employs a two-dimensional photonic band gap structure to achieve in-plane confinement of light and uses index contrast to achieve vertical confinement. We discuss how this material can be used to create microcavities for the production of low threshold lasers and waveguides capable of low-loss bends.
