- Abstract
We have built a simple line-by-line spectral intensity coder with 4 GHz resolution at 1.55 µm using a grating, a collimating lens, and an intensity mask. By applying a 10 GHz mode-locked spectral comb to the coder, we have generated relatively stable 20 - 100 GHz pulse trains with 10 GHz steps. The characteristics of generated pulse trains are examined quantitatively by measuring the corresponding optical spectra, time-domain waveforms, autocorrelation traces, and radio- frequency spectra.
