The microcavity is made of a pair of quantum wells (white-red-white layers) sandwiched by two Bragg mirrors (alternation of light blue and dark blue layers); the green layer is the substrate.
Aberration, in optical systems, such as lenses and curved mirrors, the deviation of light rays through lenses, causing images of objects to be blurred.
And A Mirror Of Whitening Light, composed for the London Sinfonietta 11 years later, was one of the pieces that defined his later iridescent sound world.
The programme concludes with one of Maxwell Davies's masterpieces, A Mirror of Whitening Light, a savagely complex evocation of the sky and sea surrounding the composer's Orcadian croft.
A Mirror of Whitening Light, on the other hand, which Davies composed for the Sinfonietta in 1977, glittered and darted as bewitchingly as it did at its first performance.
There she demonstrated her signature principles of design: simplicity, airiness (through the use of mirrors and light hues of paint and fabric), and visual (rather than simple stylistic) unity.
On a mirrored platform strewn with ashes, a long golden pointer moves gently about, barely touching the mirror's surface as it shifts the ashes here and there, its action reflected by the mirror as streaks of light through dark clouds.
This oil spill is said to be mostly "sheen," which means a layer less than one-three-thousandth the thickness of a hair, visible only because it causes mirror-like reflection of light or radar energy.
The green space in the Park of Heroes, which originally was to mirror the Wedge of Light across Greenwich Street, has been cut roughly in half by a redesign of the Freedom Tower and the attached office building.
As the researchers moved the ion away from the mirror, the amount of light coming through the system varied by about 6%, they report in a paper to be published in Physical Review Letters.
