Title:
光制御装置
Document Type and Number:
Japanese Patent JP3989374
Kind Code:
B2
Abstract:
An optical control device capable of controlling an optical signal with another optical signal, wherein a first laser light L1 of a wavelength lambda 1 and a second laser light L2 of a wavelength lambda 2 are coupled together by a first optical coupler (24) and are input to an optical amplifying element (26), and a light of the wavelength lambda 2 which is extracted by an optical filtering element (29) from the output light of the optical amplifying element (26) and a third laser light L3 of the wavelength lambda 1 are coupled together by a second optical coupler (24') and are input to a second optical amplifying element (26'). A light of the wavelength lambda 1 is extracted by a second optical filtering element (28) from the output light of the second optical amplifying element (26'), whereby an amplified output signal lout is obtained, as shown at (a) in Fig. 10. The optical control device can generate the output light of the first wavelength lambda 1, by a switching control using the first laser light L1 of the first wavelength and the third input light of the first wavelength lambda 1.
