MEMS Phase Modulator for Ultrashort Optical Pulse Shaping

The main purpose of this research is to explore the possibility of using a micromirror array as a spatial light phase modulator for ultrashort pulse shaping. The advantage of this reflective pixelated SLPM is that it can implement a piecewise linear approximation to a desired modulation profile provided each mirror has both tilt and vertical levitation motion control. It is much more efficient and capable to generate desired optical pulses than any other technologies currently available. The background knowledge of ultrashort optical pulse shaping, theoretical and the experimental research on this device are introduced.
