Tunable chromatic dispersion compensator

2004 23rd IEEE Convention of Electrical and Electronics Engineers in Israel, 2004
One of the major bottlenecks in optical telecommunication systems is chromatic dispersion. Each frequency component of an optical pulse travels at a different group velocity, hence the pulse width broadens, thereby leading to system penalties. A demand for tunable compensators has arisen from DWDM systems with dynamic routing where the degree of pulse ...

Chromatic dispersion of soft contact lens materials

Contact Lens and Anterior Eye, 2023
To investigate and evaluate the chromatic dispersion of various hydrogel and silicon hydrogel contact lens materials.Eighteen different soft contact lens materials with high and low water content in lens power of -1.00 DS were measured by one operator at temperature of 20 °C ± 0.5° soaked in ISO standard phosphate-buffered saline (PBS) and in their ...

Laterally chromatically dispersed, spectrally encoded interferometer

Applied Optics, 2011
We present a single-shot line sensor based on spectral interferometry. Light of a broadband laser source is chromatically dispersed by a grating and focused onto a line on the surface such that each focal point on this line is formed by another wavelength.

Chromatic dispersion of the ocular media

Vision Research, 1982
Measurements of chromatic dispersion of aqueous and vitreous humors, cornea and lens of the eye are sparse and incomplete. The wavelength variation in refractive index of the ocular media of cow, pig, frog (Rana pipiens), chicken, rock bass (Ambloplites rupestris), albino rat and cat as well as human lenses was determined by means of Abbe and Pulfrich ...
