phase array (PHASAR)

The PhaseArray (PHASAR) or Arrayed Waveguide Gratings (AWG) is an optical component built in planar, integrated technology for multiplexing or demultiplexing optical wavelengths

The phase array is characterized by the fact that the phases of the individual wavelengths are constant during multi-channel multiplexing and demultiplexing.According to the method, phasars work with optical waveguides of

different lengths, which compensate for thephase shifts

at different wavelengths. Phasars work without electrical energy and belong to the components of phonetics.
