Compact Spectral Pulse Shaping using Hybrid Planar Lightwave Circuit and Free-Space Optics with MEMS Piston Micromirrors and Spectrogram Feedback Control
07 November 2004
We combine a PLC and free-space optics for a compact Fourier- plane pulse shaper with low polarization dependencies. A micromirror array with piston motion provides phase modulation.
The modulated electric field is extracted from a recorded spectrogram of the synthesized waveform.
