ABSTRACT:
An infrared light transmitting optical fiber and a process for producing the same are disclosed. The infrared light transmitting optical fiber is produced by a process comprising preparing a core crystalline fiber having a high melting point and a high refractive index, forming around the core fiber a continuous layer of cladding crystal having a low melting point and a low refractive index, and subsequently forming a protective layer on the resulting step-index fiber.
