Title: Method for generating optical pulse and method for compressing optical pulse, optical pulse generator and optical pulse compressor
Inventor: NAKAZAWA MASATAKA
IPC: G02B6/02
Filed: 2003-11-18
Abstract: <P>PROBLEM TO BE SOLVED: To generate a quadric type optical pulse with a high SN ratio.  <P>SOLUTION: A normal dispersion reducing fiber 3 is an optical fiber of which the absolute value of dispersion is reduced as going farther to a longitudinal direction. By making an arbitrarily shaped nonlinear optical pulse generated with an optical pulse transmitter 1 and amplified with an optical amplifier 2 propagate through a fiber 3 and equivalently form an optical amplification effect, the quadric type optical pulse with a parabolic shape and having a linear chirp extending over a wide band is generated. A dispersion D(z) of the fiber 3 at a coordinate z of the longitudinal direction is expressed by an equation D(z)=1/(1+Γz) based on a ratio Γ of reduction of the magnitude of normal dispersion on the fiber 3. This kind of the fiber 3 is realized by continuously varying a core diameter in the longitudinal direction, and also is realized by longitudinally connecting a plurality of kinds of optical fibers of which the dispersion is constant or linearly varies in the longitudinal direction and discretely approximating a continuous variation of dispersion for every section.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
