Which outcome characterizes single-mode laser operation in optical fiber?

A)Minimization of pulse dispersion
B)Increased power from stimulated Raman
C)Intensified four-wave mixing efficacy
D)Elevated fiber cladding backscattering

💡 Explanation

Single-mode fibers support fundamental Gaussian mode propagation. This minimizes pulse dispersion because modal dispersion is absent, therefore minimizing signal degradation rather than other nonlinear effects, different modes create multipath interference.
