Optical noise refers to undesirable fluctuations or disturbances in an optical signal that can affect the quality or integrity of the transmitted information. This type of noise is particularly...

optical parametric amplification

Optical parametric amplification (OPA) is a process in nonlinear optics where a weak signal beam is amplified by a much stronger pump beam through the nonlinear interaction in a nonlinear optical...

optical path -> optical distance

The physical length of the light path in a substance divided by the refractive index of that substance. See also equivalent air path.

optical perturbation

Optical perturbation refers to any disturbance or alteration in the characteristics of light as it propagates through or interacts with a medium. This perturbation can include changes in the...

optical phase distortion

Optical phase distortion refers to a phenomenon where the phase of an optical wavefront is altered as it propagates through a medium. This distortion can result from variations in the refractive...

optical resonator -> resonator

A resonator is a device or system that exhibits resonance, which is a phenomenon that occurs when an external force or stimulus is applied at a specific frequency, causing the system to oscillate...
