Abstract

For improvement in the performances of spatially resolved spectroscopy, optical data storage, and so on, we demonstrate here an extremely high throughput and resolution capability of a pyramidal silicon probe. Since the high refractive index of the silicon (n= 3.67, @ λ=830 nm) leads to a short effective wavelength inside the probe, which results in high throughput and spatial resolution compared to conventional fiber probes.¹
