Negative slope dispersion compensating fibers

OFC/IOOC . Technical Digest. Optical Fiber Communication Conference, 1999, and the International Conference on Integrated Optics and Optical Fiber Communication, 2003
Two types of DC fibers are presented. The first is an improved high figure of merit (267) negative slope dispersion-compensating fiber intended for DC modules. Also presented is a type II DC fiber intended for field deployment that leads to total broadband dispersion compensation.

Fiber Bragg gratings for pure dispersion-slope compensation

Optics Letters, 2003
Single-fiber Bragg gratings designed to compensate for pure third-order dispersion are demonstrated. The devices are designed by use of a layer-peeling inverse-scattering technique and exhibit dispersion profiles across their reflection bandwidths of -20, +/- 40, and -225 ps/nm2 over bandwidths of 4.5, 6, and 3 nm, respectively.

Feed-Forward Slope Compensated PFC for Chaos Control

Journal of Circuits, Systems and Computers, 2015
Based on the dual-loop control peak current mode power factor correction (PFC) converter, a feed-forward slope compensation method is proposed, which could regulate the compensated slope real-time and suppress the loop perturbation, thus controlling chaos of the system for better stability.

Current-Mode Converters with Adjustable-Slope Compensating Ramp

APCCAS 2006 - 2006 IEEE Asia Pacific Conference on Circuits and Systems, 2006
Sub-harmonic oscillation is a well-known problem in DC/DC converters with current mode control. To avoid this problem, a method to achieve adjustable-slope compensation is proposed. This method makes the compensating ramp slope appropriate for various output voltage levels. Besides solving the sub-harmonic oscillation problem, this method can also make

Compensation ability evaluation of part-compensation lens based on slope asphericity

SPIE Proceedings, 2010
The accurate evaluation on the compensation range of part-compensation lens is beneficial to guide the design of part-compensation lens and realize fast testing on many aspheric surfaces. The prior evaluation methods based on asphericity have error judge occurred, thus reduce the compensation range of part-compensation lens negatively, further ...
