The modulator may receive an optical signal. The modulator may modulate the optical signal to include a first channel and a second channel. The modulator may modulate the optical signal based on a training pattern associated with detecting a skew. The modulator may cause the first channel to interfere with the second channel. The modulator may perform a power measurement on the first channel and the second channel. The modulator may determine the skew based on the power measurement and the training pattern. The modulator may time delay the first channel or the second channel to align the skew based on the skew."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Detection and alignment of XY skew","description":"An optical device may include a modulator.
