Abstract
An integral chip is disclosed by embodiments of the present disclosure, including: two mono-mode vertical coupling gratings, two modulation modules, one 2×1 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.
