Abstract

We describe a dynamic direct space-to-time pulse shaper based on the combination of a reflective arrayed waveguide grating multiplexer and an array of digital micromirrors used as an external reflector. Spatial modulation was obtained by imposing a reconfigurable periodic structure on the digital micromirror array. The period of this structure and the number of reflecting micromirrors within each period was varied to produce pulse sequences with variable repetition rates within the burst and different pulsewidths. Experimental results are in excellent agreement with simulated temporal output response.
