It is common for two monochromators to be connected in series, with their mechanical systems operating in tandem so that they both select the same color. This arrangement is not intended to improve the narrowness of the spectrum, but rather to lower the cutoff level.

The primary application of fiber Bragg gratings is in optical communications systems. The signal is reflected back to the circulator where it is directed down and dropped ou.

This paper describes design, theoretical analysis, and experimental evaluation of a π-Phase-Shifted Fiber Bragg Grating (π-PSFBG) inscribed in the standard telecom fiber for slow light generation. At first, the grating was designed for its use in the reflection mode with a central wavelength of. in electronic engineering from the Pontifícia Universidade Católica of Rio de Janeiro in 1975 and a M. The crucial attenuation limit of 20 dB/km was first achieved in 1970 by researchers at Corning Glass Works (an American glass maker, now Corning Incorporated).

Rotary atomizers use a high speed rotating disk, cup or wheel to discharge liquid at high speed to the perimeter, forming a hollow cone spray. Atomization methods can be divided into hydraulic atomization and pneumatic atomization. The fundamental mechanisms of atomization physics, Newtonian and non-Newtonian atomization, primary and secondary breakups and disintegration of liquid jets and liquid sheets are briefl introduced, based on the up-to-date litera-ture.
