Abstract :
We demonstrate very-high-speed discrete-time filtering using optical lattice filters. We generate 667 GHz bursts of 250 fs optical pulses whose leading edges have step and ramp shaped envelopes, and convolve them with designed lattice filter system responses to produce discrete-time signals with ramp and quadratic shaped envelopes. These filters thus act as precise digital integrators.<>
