Geração de Pentes Ópticos de Frequências Amplos e Ultra Planos por Moduladores Eletro-ópticos Cascateados

An optical comb frequency generator with a large number of equalized lines by the efficient modulation of a cascade of electro-optic modulators is proposed. Modeling of the array allowed theoretical analysis of the performance and determination of the driving conditions for empirical testing of the modulators. In an array with one phase modulator followed by three dual-control Mach-Zehnder modulators, the theoretical analysis produced combs with up to 65 equalized spectral lines. In an experimental test with one modulator of each type and the same arrangement, a comb of 25 equalized lines was obtained, which is consistent with theory.
