An optical pulse train generator is composed of first and second optical resonators and an optical pulse generator. The first optical resonator has therein a first optical path of a first optical path length. The second optical resonator is inserted into the first optical path. The second optical resonator has therein a second optical path of a second optical path length substantially equal to 1/m of the second optical path length, m being a natural number. The optical pulse generator provides the first optical resonator with a first optical pulse train including a component of a first repetition rate tuned corresponding to the first optical path length. The provision of the first optical pulses allows a second optical pulse isolator to be generated in the first optical resonator. The first optical resonator extracts a portion of the second optical pulse train to output an output optical pulse train.
