| Abstract | We experimentally characterize the performance of a continuously tunable all-optical complex-coefficient finite-impulse-response (FIR) filter that exploits nonlinear signal processing (multiplexing and multicasting) and conversion-dispersion-based optical delays. Various length (three and four) optical FIR filters with different tap amplitudes (from 0 to &\#x2212;9&\#x2009;&\#x2009;dB), tap phases (from 0 to 2&\#x3C0;), and tap delays (&\#x223C;37.4&\#x2009;&\#x2009;ps and 25&\#xA0;ps) are realized, showing reconfiguration and tuning capabilities of this FIR filter. The measured frequency responses show close agreement with the theoretical filter responses. |
