1. A method for communication, the method comprising:

  • in an integrated circuit comprising an optoelectronic transceiver, a multi-wavelength grating coupler, and first and second optical sources coupled to the integrated circuit;

    coupling a first source optical signal at a first wavelength into the integrated circuit using the first optical source;

    coupling a second source optical signal at a second wavelength different from the first wavelength into the integrated circuit using the second optical source;

    receiving a first optical data signal at the first wavelength from an optical fiber coupled to the multi-wavelength grating coupler; and

    receiving a second optical data signal at the second wavelength from the optical fiber coupled to the multi-wavelength grating coupler.
