Abstract
An optical device receives a modulation format and a baud rate for transmission of an optical signal with multiple subcarrier signals, and generates the optical signal based on the modulation format and the baud rate. The optical device generates a dual-etalon response based on the optical signal, the modulation format, and the baud rate, where the dual-etalon response includes multiple peaks. The optical device compares the subcarrier signals of the optical signal and the peaks of the dual-etalon response, and determines, based on the comparing, whether at least one of the subcarrier signals aligns with a peak of the dual-etalon response. The optical device locks or adjusts a wavelength of the optical signal for the modulation format and the baud rate based on whether at least one of the subcarrier signals aligns with a peak of the dual-etalon response.
