    Abstract: An optical modulating device of the present disclosure includes an optical splitter, an optical phase modulator and an optical combiner. The optical splitter splits an inputting optical signal by an optical splitting ratio to generate a first split optical signal and a second split optical signal. The optical phase modulator phase modulates the first split optical signal and the second split optical signal to respectively generate a first modulating optical signal and a second modulating optical signal. The optical combiner combines the first modulating optical signal and the second modulating optical signal by a combining ratio to generate an outputting optical signal having a chirp, the combining ratio being equal to the optical splitting ratio, a value of the combining ratio being a positive number, and the value being less than one or more than one.

    Abstract: The present disclosure provides a photonic integrated circuit chip. The photonic integrated circuit chip comprises a plurality of connection ports, multiple polarization beam splitting structures, a photodetector structure, an interleaver and a modulator. The plurality of connection ports are used to receive a plurality of first optical signals to the photonic integrated circuit chip. The multiple polarization beam splitting structures each are used to split the first optical signal passing through the polarization beam splitting structure into a first mode optical signal and a second mode optical signal. The photodetector structure comprises a first component for split beam and a second component for split beam. The interleaver is used to transfer the first mode optical signal or the second mode optical signal to the second component for split beam. The modulator is used to transfer second optical signals with different wavelengths to the interleaver. The interleaver further transfers the second optical signals to the different connection ports according to the different wavelengths of the second optical signals.
