Two-dimensional beam steering based on hitless wavelength-selective switch array
We propose a two-dimensional beam scanner based on hitless microring switch array. By changing the resonance state of the microring interference between different wavelength selection switches is avoided. The operation complexity of the beam steering FPA chip based on the microring switch array is reduced.
