Title OPTICAL SIGNAL AMPLIFYING TRIODE AND OPTICAL SIGNAL TRANSFER METHOD, OPTICAL SIGNAL RELAY DEVICE, AND OPTICAL SIGNAL STORAGE DEVICE USING THE SAME
Abstract

When in an optical signal amplifying triode 10, light of a second wavelength .lambda.2, selected from among light from a first optical amplifier 26, into which a first input light L1 of a first wavelength A1 and a second input light L2 of second wavelength .lambda.2 have been input, and a third input light (control light) L3 of a third wavelength .lambda.3 are input into a second optical amplifier 34, an output light L4 of the third wavelength .lambda.3, selected from among the light output from the second optical amplifier 34, is light that is modulated in response to the intensity variation of one or both of the first input light L1 of the first wavelength .lambda.1 and the third input light L3 of the third wavelength .lambda.3 and is an amplified signal, with which the signal gain with respect to the third input light (control light)

L3 of the third wavelength .lambda.3 is of a magnitude of 2 or more. An optical signal amplifying triode 10, which can directly perform an optical signal amplification process using control input light, can thus be provided.
