On the Chromatic Dispersion of Hydrophobic and Hydrophilic Intraocular Lenses
Optometry and Vision Science, 2020SIGNIFICANCE There is a high variation of chromatic dispersion with contemporary intraocular lens (IOL) materials. It is well known that chromatic aberration limits the optical performance especially with high‐power lenses.

On-line simultaneous monitoring of polarization mode dispersion and chromatic dispersion
Applied Optics, 2006We have developed new expressions for power fading and average power fading owing to polarization mode dispersion (PMD) and chromatic dispersion in terms of the angle of precession of the output state of polarization about the PMD vector. Based on these expressions, a simple and novel pilot-tone-based technique for simultaneous monitoring of chromatic ...

Employing dispersion-flattened fiber for chromatic dispersion measurement
Optical Engineering, 2006A new technique for measuring the accumulated chromatic dispersion (CD) in single-mode fiber (SMF) is presented. The technique uses the ratio of the beating power between pump and probe signals and the beating power between probe signal and the four-wave mixing (FWM) conjugated signal.

Laterally chromatically dispersed, spectrally encoded interferometer
Applied Optics, 2011We 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.

Effect of Chromatic Dispersion of a Lens on Visual Acuity
Optometry and Vision Science, 1988ABSTRACT Materials with a high refractive index have a considerable level of chromatic dispersion which, around the periphery of corrective lenses, may affect the wearer's visual acuity. By measuring visual acuity through prisms of increasing chromatic power we have established the relation between chromatic power and visual acuity ...

Chromatic dispersion and losses of microstructured optical fibers
Applied Optics, 2003Using a rigorous and vector multipole method, we compute both losses and dispersion properties of microstructured optical fibers with finite cross sections. We restrict our study to triangular lattices of air-hole inclusions in a silica matrix, taking into account material dispersion. The fiber core is modeled by a missing inclusion.

Modules for chromatic dispersion and dispersion slope management
Optical Fiber Communication Conference and Exhibit, 2002Dispersion management of high-speed, broadband, long-distance networks calls for continuous full-slope matching of all DWDM channels, as well as low insertion loss, low PMD and low sensitivity to non-linear effects. Dispersion compensation via the fundamental mode meets most requirements, but is inherently accompanied by very small effective areas ...

Evaluation of chromatic dispersion in W-type fibers
Optics Letters, 1989Evaluation of chromatic dispersion in W-type fibers, based on the assumption that waveguide and material dispersion are additive effects, is examined. Actual and approximate dispersion of the LP(01) mode are calculated and compared for three W fibers. For two fibers the errors introduced by the approximate method are substantial, even larger than the ...

Optically tuning of chromatic dispersion compensators
International Conference on Advanced Infocomm Technology 2011 (ICAIT 2011), 2011We present a new tuning method for chromatic dispersion compensators, which can be optically tunable. The dispersion compensators were made in Er/Yb co-doped fiber and were pumped with 980nm laser diodes. The tunable dispersion for a chirped grating and also a uniform-period grating was successfully demonstrated in the experiment.
