A broadband tuning system includes a first chip and a second chip. The first chip includes a first light amplification region, a first forward grating region and a first backward grating region that are sequentially arranged in a first direction. The first light amplification region is configured to amplify a first light source and to turn on or turn off the first light source, and the first forward grating region and the first backward grating region are configured to tune the first light source. The second chip includes a second light amplification region, a second forward grating region and a second backward grating region that are sequentially arranged in a second direction. The second light amplification region is configured to amplify a second light source and to turn on or turn off the second light source, and the second forward grating region and the second backward grating region are configured to tune the second light source.

Broadband tuning system and method

An integral chip is disclosed by embodiments of the present disclosure, including: two mono-mode vertical coupling gratings, two modulation modules, one 2&#xd7;1 multi-mode interference coupler, and one dual-mode vertical coupling grating. The integral chip is capable of operating in dual wavelengths and dual polarization states by combination of polarization multiplexing and wavelength division multiplexing so as to realize modulation of complex formats and to enhance data modulation rate.
