A step-index fiber is constructed with n1 = 1.450, n2 = 1.445, and radius a = 4.0 um. (a) Will this fiber be single mode when the operating wavelength is A = 1.55 um? (b) Evaluate the cutoff wavelength Ac (for LP11) of this fiber. (c) If the operating wavelength is A = 0.488 um, which LP modes will propagate?
