अपवर्तनी-सूचकांक इसके अंग्रेजी अर्थ का उदाहरण

The refractive index profile is enhanced for VCSEL transmission and to prevent pulse spreading.

This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a wavelength-specific dielectric mirror.

Fiber Bragg gratings are created by "inscribing" or "writing" systematic (periodic or aperiodic) variation of refractive index into the core of a special type of optical fiber using an intense ultraviolet (UV) source such as a UV laser.

The germanium-doped fiber is photosensitive, which means that the refractive index of the core changes with exposure to UV light.

The refractive index of the photosensitive fiber changes according to the intensity of light that it is exposed to.

The refractive index will typically alternate over a defined length.

where \scriptstyle n_e is the effective refractive index of the grating in the fiber core and \scriptstyle \Lambda is the grating period.

The effective refractive index quantifies the velocity of propagating light as compared to its velocity in vacuum.

where \scriptstyle \delta n_0 is the variation in the refractive index (\scriptstyle n_3 \,-\, n_2), and \scriptstyle \eta is the fraction of power in the core.

The structure of the FBG can vary via the refractive index, or the grating period.

The refractive index has two primary characteristics, the refractive index profile, and the offset.

Typically, the refractive index profile can be uniform or apodized, and the refractive index offset is positive or zero.

This is apodization of the refractive index change.
