An efficient wavelength converter exploiting a grating based saw-tooth pulse shaper
IEEE Photonics Technology Letters, 20, (17), . (doi:10.1109/LPT.2008.927887).
We experimentally demonstrate the generation of picosecond triangular optical pulses using a superstructured fiber Bragg grating and show experimentally that use of this pulse shape can provide a three-fold improvement in conversion efficiency relative to the use of Gaussian pulses with similar pulse widths when used in a wavelength conversion scheme based on self-phase-modulation and subsequent offset filtering.
