We present a scalable approach to optical time division multiplexing using an all-optical transmultiplexer incorporating a time lens. With simply a single nonlinear device we numerically demonstrate direct conversion from time-division multiplexing (TDM) to wavelength division multiplexing (WDM) with an industry standard 100-GHz channel spacing. Data rates at 1.28 Tb/s are realized in simulation. Additionally, various pump shapes are investigated to minimize distortions and reverse operation of the device (WDM to TDM conversion) is shown.
