Limiting-eye patterns (LEPs) for various types of optical modulators are constructed from the inverse Fourier transform of the frequency-domain voltage-length integral (VLI). Various transmission-line circuits for low-characteristic-impedance (typically 23 /spl Omega/) modulators are optimized on the basis of the maximum opening of the LEP. The results show that localized pad capacitances, when used in combination with sections of a high-impedance (typically 75 /spl Omega/) transmission line… CONTINUE READING
