Abstract

In this study, we present simulation studies of an intensity modulation technique to produce an optical pulse train. This technique used two optical phase modulators connected to a Fabry-Perot filter (with a free spectral range of 200 GHz and finesse of 500) connected in series to a fiber. Short RF pulses with a phase difference of 180 degrees induced the optical phase modulators. A digital phase shifter created a 180-degree phase difference between RF signals. In the simulation studies, the technique was investigated in a ring-cavity laser design model at the laser wavelength of 1300 nm. Optical pulses were obtained at a repetition rate of 100 MHz with a pulse width of about 600 ps. It was possible to change the optical pulse parameters by changing the bit sequence configuration and bit-rate of the digital phase shifter. With further improvement in effective control of rapid phase shift between RF signals, the technique can be used in active modelocking.
