Copper load in Mute Swans (Cygnus olor) found in Denmark.

Abstract

We demonstrate that combined lateral-vertical oxidn. of AlGaAs can be used to change the resonant wavelength of an optical cavity after the single epitaxial growth. A multiple-wavelength array of vertical-cavity surface-emitting lasers with a 48 nm wavelength span was realized using this technique. [on SciFinder (R)]
