neaspec’s neaSNOM microscope allows for launching and controlling light propagating along graphene, opening new venues for extremely miniaturized photonic devices and circuits
Two independent research teams have successfully used their neaSNOM infrared near-field microscopes for laying down a ghost: visualizing Dirac plasmons propagating along graphene, for the first time.
Near-field imaging of resonant gold nanodiscs reveals a dipolar oscillation mode.
Infrared near-field microscopy allows to study the propagation of surface waves in the infrared spectral regime. Amplitude and phase resolved near-field images reveal local interference effects or enable the determination of the complex wave vector of surface waves. Surface waves can be excited in the mid-infrared spectral regime by e.g. metal structures on Silicon Carbide…
Direct verification of superlensing can be achieved by near-field microscopy as the local field transmitted by a superlens can be investigated in the near-field of the lens.
Direct visualization of infrared light transportation and nanofocusing by miniature transmission lines is possible by amplitude- and phase-resolved near-field microscopy.
Amplitude and phase resolved near-field mapping of the local field distribution on resonant IR antennas can be used to analyze the antenna design and its functionality.
