Optical storage is any storage method in which data is written and read with a laser for archival or backup purposes. Typically, data is written to optical media, such as CD s and DVDs. For several years, proponents have spoken of optical storage as a near-future replacement for both hard drive s in personal computers and tape backup in mass ...

But it also means more dispersion of the signals. The acceptance angle is related to the numerical aperture (NA) of the fiber: NA = sin (acceptance angle) So a fiber with NA of 0.2 means the maximum acceptance angle is sin-1 (0.2) = 11.5 degrees. The key points are: Acceptance angle is the max input angle for light to propagate.

BD supports write-once, read-only, and rewritable discs as well as multilayer discs to increase the storage under the optical head. Capacity is limited by optical absorption, spherical aberration, and SNR of the optical signals through the layers. Double- or triple-layer BD discs are required for UHDTV video.

Optical resonance occurs when the optical feedback is in phase with the intracavity optical field. The optical feedback in a Fabry–Pérot cavity is provided simply by the two end mirrors that have the reflective surfaces perpendicular to the longitudinal axis, as in Figs. 6.1 (a) and (b). In a ring cavity, it is provided by the circulation of ...
