摘要： 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.

摘要： A tunable laser with multiple in-line sections generally includes a semiconductor laser body with a plurality of in-line laser sections each configured to be driven independently to generate laser light at a wavelength within a different respective wavelength range. The wavelength of the light generated in each of the laser sections may be tuned, in response to a temperature change, to a channel wavelength within the respective wavelength range. A switch module may be configured to couple a signal from a laser driver to a selected one of the plurality of in-line laser sections, wherein the signal modulates the laser light generated by the in-line laser section. The selected in-line section may be DC biased to a lasing state and the non-selected in-line sections may be DC biased to a non-lasing or transparent state.
