An ultrawide‐band unidirectional surface plasmon polariton launcher is realized by X. Y. Hu, Q. H. Gong, and co‐workers, who combine plasmonic bandgap engineering and a linear interference effect on a gold–polymer platform. This device is easy to fabricate, operates over an ultrabroad wavelength range from 690 to 900 nm, and has a large extinction ratio of 30 dB and small feature size of 3.9 μm. On page 792, this device provides an excellent optical source on chip for future optical computing technologies and may pave the way to constructing novel nanophotonic processor architectures.
