Classification: CPC H | IPC H

Claim 17:
18. In a communication system comprising: a transmitter comprising a first optical module, the first optical module comprising a plurality of Micro-Ring Modulators (MRMs), a receiver comprising a second optical module, the second optical module comprising a plurality of Ring Resonator Modules (MRRs),
wherein the first optical module and the second optical module are connected by an optical waveguide, and at least one comb laser external to an optical co-package comprising the transmitter or the receiver, the at least one comb laser irradiating the optical waveguide, the at least one comb laser emitting light in a plurality of wavelengths,
wherein at least one first MRM and at least one first MRR are adjusted to operate in at least one first wavelengths from the plurality of wavelengths, and at least one second MRM and at least one second MRR are adjusted to operate in at least one second wavelength from the plurality of wavelengths,
wherein the at least one first MRM and at least one first MRR are adjusted to operate at the first wavelength using a first predetermined training sequence, and the at least one second MRM and at least one second MRR are adjusted to operate at the second wavelength using a second predetermined training sequence, and
wherein the first predetermined training sequence is different from the second predetermined training sequence, and wherein training sequences for different MRM-MRR pairs are orthogonal to each other,
a method for adjusting the plurality of MRMs, the method comprising:
for each MRM from the plurality of MRMs:
swinging an MRM ring temperature or the bias voltage of a first MRM from the plurality of MRMs until maximum light is detected in a drop output; and
changing modulation of the MRM until a minimum is detected in non-invasive detector at an end of a line of the first MRM.
