Liquid Fundamental Measurements on an Aggregated Dye Crystal
... The liquid crystal phase of matter interests researchers for many reasons , mostly involving optical properties not seen in other fluids along with a sensitivity to external conditions. These properties have made liquid crystals useful particularly in display devices. Despite the importance of liqui ...

PASSION FOR PRECISION
... A number of European laboratories did better, notably the Observatoire in Paris (now BNM SYRTE) and the Physikalisch-Technische Bundesanstalt (PTB) in Braunschweig. In an article published in early 1996 [26], a team from the PTB laid claim to the first phase coherent frequency measurement of visible ...

Semiconductor optical amplifier-based all-optical gates
... 168 Gb/s [57]. High-speed operation has also been achieved, using nonlinear loop mirrors with SOAs demonstrating demultiplexing from 250 Gb/s [58]. For demultiplexing of OTDM signals, the semiconductor-based interferometers do not yet achieve the speed of fiber-based NOLMs (e.g., [59]), but they hav ...

As one can see from Table I, there are three groups of physical laws that change when turning from the nonmagnetic approach equations to the exact expressions. Snellius’ law, Doppler and Cherenkov effects are√in the first group. In their formulas, the expression n ...

Retroreflector
A retroreflector (sometimes called a retroflector or cataphote) is a device or surface that reflects light back to its source with a minimum of scattering. In a retroreflector an electromagnetic wavefront is reflected back along a vector that is parallel to but opposite in direction from the wave's source. The angle of incidence at which the device or surface reflects light in this way is greater than zero, unlike a planar mirror, which does this only if the mirror is exactly perpendicular to the wave front, having a zero angle of incidence.
