Patent attributes
In the optical module, the number of optical components is decreased, so that the costs of the device are reduced, and so that optical loss is reduced. The present device comprises: an optical gate array in which a plurality of optical gate switches each employing a semiconductor optical amplifier element are arranged in parallel; a dividing/combining unit including: a plurality of first ports connected one to each of the plurality of optical gate switches forming the optical gate array; and a second port which performs dividing/combining of light with the first port; and an optical amplifier connected to the second port of the dividing/combining unit, wherein the optical gate array, the dividing/combing unit, and the optical amplifier are formed in an integrated manner.
