The nanoscope can deliver a high-intensity spot (greater than 40 mW/μm2) with a near-field spot size of less than 50 nm in diameter.
Stanford scientists have developed a nanoscope consisting of integrated VCSEL arrays bonded to arrays of nanoaperture tips. This versatile device can serve as an AFM and/or near-field probe for a variety of applications such as heat-assisted recording, optical interconnects or single-molecule detection. The nanoscope can deliver a high-intensity spot (greater than 40 mW/μm2) with a near-field spot size of less than 50 nm in diameter. A sharp tip can be incorporated to the nanoaperture to achieve sub-20 nm resolution.
A wide range of near-field applications
Ultrahigh-density optical data storage
Integrated light source for future nanophotonic circuits
The nano-aperture cannot be milled directly on the top surface since the focus ion beam has a 7 degrees incident angle and thus leads to tapering in the nanoaperture
The rounding along the periphery of the nano-aperture will severely compromise the resonance of the aperture
The near-field probe is only effective less than 20 nm from the emitting surface
