Polarization in a sentence

Polarization crosstalk In an ordinary (non-polarization-maintaining) fiber, two polarization modes (say vertical and horizontal polarization) have the same nominal phase velocity due to the fiber's circular symmetry.

Additionally, multiple polarization signals can be combined (i.e. interfered) to form new states of polarization, which is known as parallel polarization state generation.

For a linear input polarization (often oriented at 45° to the crystal axis), the output polarization will in general be elliptical, rather than simply a linear polarization state with a rotated direction.

Note that linear polarization and circular polarization can be seen as special cases of elliptical polarization.

Polarization-division multiplexing Polarization-division multiplexing uses the polarization of electromagnetic radiation to separate orthogonal channels.

Polarization statemain further Electric field oscillation Polarization is best understood by initially considering only pure polarization states, and only a coherent sinusoidal wave at some optical frequency.

Sea clutter can be reduced by using horizontal polarization, while rain is reduced with circular polarization (note that meteorological radars wish for the opposite effect, and therefore use linear polarization to detect precipitation).

The output of an ideal polarizer is a specific polarization state (usually linear polarization) with an amplitude equal to the input wave's original amplitude in that polarization mode.

By exciting the system linearly, this hybrid nanoplatform can switch between four upconversion polarization states, allowing multiple levels of light output in parallel or orthogonal polarization configurations.

The electric polarization controller (EPC) and the polarizer together produce artificially saturated absorption in nonlinear polarization evolution (NPE)-based mode locking.

The polarization of American politics has long been in the making and predates TrumpThe polarization of American politics has long been in the making and predates Trump.

AM and FM broadcast radio usually use vertical polarization, while television uses horizontal polarization.

At most points along the fiber the net polarization will be an elliptically polarized state, with a return to the original polarization state after an integer number of beat lengths.

By appropriate choice of the relationship between these parameters, it is possible to introduce a controlled phase shift between the two polarization components of a light wave, thereby altering its polarization.

Depending on the thickness of the crystal, light with polarization components along both axes will emerge in a different polarization state.

Fluorescence anisotropy can be defined quantitatively as : where is the emitted intensity parallel to polarization of the excitation light and is the emitted intensity perpendicular to the polarization of the excitation light.

For coherent transmitter and receiver, the PER is a key parameter since X-polarization and Y-polarization are coded with different signals.

However, for understanding electromagnetic waves and polarization in particular, it is easiest to just consider coherent plane waves; these are sinusoidal waves of one particular direction (or wavevector ), frequency, phase, and polarization state.

However, in order to also describe the degree of polarization, one normally employs Stokes parameters (see below) to specify a state of partial polarization.

However, in the case of circular (or elliptical) polarization, the handedness of the polarization state is thereby reversed, since by convention this is specified relative to the direction of propagation.
