Soliton pulse compression optical fiber and method for making soliton pulse compression optical fiber

An optical fiber preform of a soliton pulse compression optical fiber for width compression of an injected light pulse, comprising:

• a core preform for a core of said soliton pulse compression optical fiber, a diameter of which decreases along a longitudinal direction of the optical fiber preform to reduce dispersion along the longitudinal direction of the optical fiber preform;
• and
• a clad preform that surrounds said core preform;
• wherein a maximum relative index difference between said core preform and said clad preform is between about 1.2% and 2.5%, and
• said dispersion decreases more than 10 ps/nm/km from an input end of the optical fiber to an output end of the optical fiber.

A method for making an optical fiber preform of a soliton pulse compression optical fiber for width compression of an injected light pulse, comprising the steps of:

• preparing a core preform for a core of said soliton pulse compression optical fiber, such that a diameter of the core decreases along a longitudinal direction of the optical fiber preform to reduce dispersion along the longitudinal direction of the optical fiber preform;
• and
• forming a clad preform that surrounds said core preform;
• whereby a maximum relative index difference between said core preform and said clad preform is between about 1.2% and 2.5%, and
• said dispersion decreases more than 10 ps/nm/km from an input end of the optical fiber to an output end of the optical fiber.
