Abstract
A photonics integrated system is disclosed, comprising a substrate, an integrated interferometer integrated in the substrate and being configured for receiving radiation from a radiation source, and an integrated spectral filter integrated in the substrate and being configured for receiving radiation from the interferometer. The integrated interferometer has a period and the integrated spectral filter has a bandwidth such that the period of the integrated interferometer is smaller than the bandwidth of the integrated spectral filter. The integrated spectral filter has a periodic transfer characteristic with a period and the system has a bandwidth such that the period of the periodic transfer characteristic of the integrated spectral filter is larger than the bandwidth of the system.
