摘要： A process and an apparatus for producing a preform for plastic optical fiber having a refractive index distribution in which the refractive index is gradually decreased from the center of the preform toward the outer periphery thereof, by depositing a deposition layer comprising a polymer A (refractive index: N.sub.a) and a refractive index modifier having a refractive index different from that of the polymer A onto a surface of a rod member rotating about an axis thereof, by use of vapor-phase deposition based on a CVD (Chemical Vapor Deposition) process, or a coating process. A plastic optical fiber preform comprising deposition layers having a gradually decreasing refractive index distribution is formed by changing the mixing ratio between the polymer A and the refractive index modifier constituting the deposition layer.

摘要： A winding reel for optical fiber is provided with a drum and a flange. The flange is provided with first and second slits therein for receiving leading and trailing (frontward and rearward) portions of the optical fiber. The length of the slit that receives the forward end of the optical fiber extends from the outer periphery of the flange to the surface of the drum. The slit for receiving the rearward end of the optical fiber is shorter than the forward end receiving slit. The rearward end receiving slit extends from the outer periphery of the flange inwardly a distance such that the slit does not reach a position at which a maximum amount of optical fiber wound on the winding reel is located.

摘要： An optical switch for switching an optical path by changing the refractive index of the circumference of a light coupling region of a directional coupler is disclosed. Such a change is accomplished by a photochromic compound in the circumferential medium of the light coupling region. Such a photochromic compound when beamed with light of a specific wavelength undergoes a photochromic reaction which changes the refractive index of the circumferential medium of the light coupling region. Such a reaction is reversible when beamed with light of another specific wavelength.
