Optical fiber probe using an electrical potential difference and an optical recorder using the same

摘要

An optical fiber probe generates an electrical potential difference formed between thin metal layers coated thereon to increase a light transmission rate. The optical fiber probe includes a near-field probe having a core transmitting light incident from an external light source and having a circular cone structure formed on an end of the core, and a cladding coated on a surface of the circular cone structure core to protect the core. The optical fiber probe also includes the thin metal layers coated on the near-field probe, symmetrically disposed on opposite sides of the near-field probe, and spaced-apart from each other to generate the electrical potential difference.
