Abstract:
An optical fiber that communicates in a predetermined communication band includes: a signal light propagation core that propagates light beams of up to (x+1)-th order LP mode, where x is an integer of two or more; and a coupler that propagates a light beam that is: coupled with a light beam of the (x+1)-th order LP mode propagating through the signal light propagation core, and suppressed from being coupled with light beams of up to the x-th order LP mode propagating through the signal light propagation core, wherein, mode coupling of the light beams of up to the x-th order LP mode propagating through the signal light propagation core is performed, and mode coupling between the light beam of the x-th order LP mode and the light beam of (x+1)-th order LP mode is suppressed.

Claim (Index 9):
The optical fiber according to  claim 8 , wherein relationships (1) to (4) below are satisfied:\n \u0394n eff a<\u0394n eff c; \u2003\u2003(1): \u0394n eff a<\u0394n eff d; \u2003\u2003(2): \u0394n eff b<\u0394n eff c; and \u2003\u2003(3): \u0394n eff b<\u0394n eff d, where \u2003\u2003(4): \u0394n eff a is a maximum value among effective refractive index differences between light beams of LP modes having effective refractive indexes that are adjacent to each other except for the x-th order LP mode and the (x+1)-th order LP mode, \u0394n eff b is a minimum value among differences between the effective refractive indexes of the light beams of (x+1)-th order LP mode and higher propagating through the signal light propagation core and an effective refractive index of a light beam of at least one mode propagating through the side core, \u0394n eff c is a difference between an effective refractive index of the light beam of the x-th order LP mode and an effective refractive index of the light beam of (x+1)-th order LP mode, and \u0394n eff d is a minimum value among differences between the effective refractive index of the light beam of the x-th order LP mode and the effective refractive indexes of the light beams of the modes propagating through the side core.
