Generation of Arbitrary Sequences of Ultrafast Pulses With Integrated-Optic Space-to-Time Optical Processors and Phase-Only Masks

We report a new approach to the generation of arbitrary sequences of ultrafast pulses using an integrated optics space-to-time optical processor. The processor combines a reflective arrayed waveguide grating multiplexer with a phase-only mask containing sets of pixels of constant phase separated by sets of pixels with phases alternating between 0 and $\pi$ rad.
