We fabricated ultrafast nonlinear optical films of squarylium J-aggregates and studied their properties including the absorption spectrum, the refractive index, the third-order nonlinear optical coefficients, the extent of absorption saturation, and the recovery of absorption saturation. The transmittance of the film was increased by 30% due to absorption saturation at a pump energy of several hundreds fJ/μm^2pulse. The half decay time constant of absorption saturation was found to be approximately 100fs for off-resonant excitation. Two-dimensional demultiplexing was demonstrated using the squarylium film as a switching material From a train of 8 optical pulses with 100fs duration and 1 ps interval corresponding to a bit rate of 1 Tbps, 2×4 spatially resolved spots were obained.
