| Research Abstract |
We have studied configurations of the optical circuits for gain detection of optical amplifiers used in photonic networks, which circuits use an independent operation type of gain control scheme. The optical amplifiers used are erbium-doped fiber amplifiers(EDFAs), especially, the L-band EDFAs, which are indispensable for large-capacity photonic networks, and semiconductor optical amplifiers(SOAs). We have confirmed the basic operation characteristics of the scheme which detects signal gain by measuring spontaneous emission light powers from optical amplifiers, which are the L-band EDFAs and SOAs. We have also clarified the accuracy of the detected gains for EDFAs.
