Abstract

A method for preparing near-field optical fiber probe includes using HF acid corrosion to process optical fiber to form reduced front-end diameter in certain conical angle, using plastic solution to clad said conical unit of optical fiber and curing plastic solution to form plastic film on surface of optical fiber, inserting prepared optical fiber HF acid with oil protection for corroding said optical fiber and using organic solvent to remove off plastic film on surface of said optical fiber to obtain near-field optical fiber probe.

Description

technical field

[0001] The invention belongs to the technical field of preparation of core components of optical precision instruments, and relates to a method for preparing a near-field optical fiber probe, in particular to a method for preparing a high-quality near-field optical fiber probe by pretreating an optical fiber and then corroding it. Background technique

[0002] As an important optical instrument, scanning near-field optical microscope (SNOM or NOSM) is widely used in the fields of physics, chemistry, material science, life science, geology and information industry. As a new member of the scanning probe microscope family, it is mainly used to observe and study the appearance, morphology and optical properties of objects at the nanoscale and mesoscopic scale. Among them, the use of SNOM to conduct spectral research on low-dimensional mesoscopic systems at the nanoscale is the core of SNOM. One of the important applications. How to effectively improve the collec...
