A fractal-based fibre for ultra-high throughput optical probes(opticsinfobase.org) A core component of all scanning near-field optical microscopy
(SNOM) systems is the optical probe, which has evolved greatly but still
represents the limiting component for the system. Here, we introduce a
new type of optical probe, based on a Fractal Fibre which is a special class
of photonic crystal fibre (PCF), to directly address the issue of increasing
the optical throughput in SNOM probes. Optical measurements through
the Fractal Fibre probes have shown superior power levels to that of
conventional SNOM probes. The results presented in this paper suggest
that a novel fibre design is critical in order to maximize the potential of the
SNOM. |
