Abstract: A photonic integrated circuit including having a semiconductor substrate having integrated a semiconductor light source, the semiconductor light source comprising: an optically active section comprising a gain section and configured to support a first number of wavelengths, an optically passive section comprising a passive waveguide optically coupled to the optically active section and a passive section mirror optically coupled to the passive waveguide, wherein the optically passive section is configured to support a second number of wavelengths that is lower than the first number; and the optically passive section further comprising a signal shifting structure configured to shift a signal of the light supported by the passive waveguide.
