Abstract:
A plastic optical fiber continuous optical amplifier comprising:irradiation means for irradiating a pump light at a specified wavelength, said irradiation means being a pump light irradiation device and including inner and outer tubes, an exciting gas sealed between the inner and outer tubes, and electrodes disposed at two ends of the tubes; anda plastic optical fiber disposed in the irradiation means and having an induced emission material doped into the plastic optical fiber in a dope area, said induced emission material having an absorption wavelength range including the pump light wavelength of the irradiation means, said dope area having a length corresponding to a length of the irradiation means so that a signal light passing through the plastic optical fiber is optically amplified by the pump light of the irradiation means continuously irradiated to the plastic optical fiber.
