Abstract

This paper reports a novel optical-time-division-mutliplexing (OTDM)/ wavelength-division-multiplexing (WDM) source based on spectral slicing of a Kerr-lens mode-locked Cr⁴⁺-YAG femtosecond laser. This mode-locked laser produces bandwidth-limited pulses having durations of 70 fs and corresponding spectral widths of 40 nm. This bandwidth is sufficiently large that an arrayed-waveguide grating (AWG) could be employed to spectrally slice the laser output into 32 different wavelength channels. A total capacity of 1.36 Tb/s (32 × 40.64 Gb /s) with measured Q factors of 8 to 13 is achieved. The spectral efficiency is 0.4 b/s/Hz.
