NLS-Glossary

is the transmission of information in the form of pulses from one location to another. Typically, an analog signal is sampled at fixed intervals and the value at each interval is put into a binary code containing 1s and 0s and the coded information is then transmitted as pulses (1corresponding the presence and 0 to the absence of a pulse). 

Thus the analog signal is digitized and sent by pulses.

Diode (short diode) is a pn junction in which the neutral regions are shorter than the minority carrier diffusion lengths.

Coupling the light from a fiber coupled laser diode into an active fiber is a complicated process. This is especially true for MOPA configurations where both the input seeder source and the pump light need to be injected.

Dipolar (orientational) polarization arises when randomly oriented polar molecules in a dielectric are rotated and aligned by the application of a field so as to give rise to a net average dipole moment per molecule.

In the absence of the field the dipoles (polar molecules) are randomly oriented and there is no average dipole moment per molecule. In the presence of the field the dipoles are rotated, some partially and some fully, to align with the field and hence give rise to a net dipole moment per molecule.
