We demonstrate line-by-line pulse shaping control for optical arbitrary waveform generation (O-AWG). Independent manipulation of individual spectral lines from a mode-locked frequency comb leads to synthesis of user-specified ultrafast optical waveforms with unprecedented frequency resolution.

Reconfigurable all-optical code translation are demonstrated in a spectrally phase-coded optical-code-division multiple-access (O-CDMA) testbed with an interference user. For both one-stage and two-stage code translations, less than 0.9-dB power penalties are induced at each code translation. Multistage code translations are investigated via simulation and experimental emulation in a loop pulse shaper to show the potential application of the proposed method for up to several tens of code translations.

We experimentally demonstrate spectral line-by-line pulse shaping. The shaped pulses overlap in time, which leads to observable fluctuations due to comb-offset frequency variations. Preliminary results of arbitrary waveform generation based on this technique are also presented.

We have experimentally demonstrated 4-user, 10 Gbit/s spectrally phase coded O-CDMA using low power nonlinear processing in two implementations, with emphasis on different coding schemes and requirements of timing coordination.

We demonstrate a 4/spl times/10 Gb/s spectrally phase coded O-CDMA system with ultra-low power (/spl sim/ 30 fJ/bit). Full interference suppression is achieved using a spectral phase correlator based-on SHG in a PPLN waveguide and double Hadamard coding.

We demonstrate generation of a high repetition rate femtosecond pulse train using the line-by-line shaping technique on a phase-modulated CW laser. Resulting pulses with FWHM duration of 324 fs at 9 GHz repetition rate are reported after soliton compression
