Carbon nanotube polycarbonate composites with controlled nanotube‐bundle size are prepared by dispersion with conjugated polymers followed by blending with polycarbonate. The composite has uniform sub‐micrometer nanotube bundles in high concentration, shows strong nonlinear optical absorption, and generates 193 fs pulses when used as passive mode‐locker in a fiber laser.
