Demonstration of a Spectrally-Partitioned $4\mathrm{x}4$ Crossbar Switch with 3 Drops per Cross-point

We present the theory and realization of a spectrally-partitioned $4\mathrm{x}4$ crossbar switch, with three microrings per cross-point having disjoint resonance regions within an FSR. We also describe an associated energy efficient, non-blocking wavelength assignment algorithm.
