Abstract
Nanophotonics In the generation of electromagnetic fields, light can be broken down into two components: the far field, which we generally see and is caused by propagating waves, and the near field. The near field presents the nonpropagating component of the electromagnetic field at subwavelength distance from the source of radiation. Probing the near field, however, can also provide detailed, subwavelength information about the emitting source. Ginis et al. present a nanophotonic-based method for controlling and manipulating the near-field landscape. This approach provides the possibility of exploiting the near-field component of light for on-chip applications that would normally require bulky optics. Science , this issue p.
