Abstract
An integrated optical device includes: a housing; a liquid-crystal optical power attenuator, an optical splitter, and an optical power monitor housed inside the housing; and first and second optical fibers housed inside the housing. The first optical fibers input an optical signal from outside the housing to the optical power attenuator. In a polarized state, the optical power attenuator attenuates the optical signal from the first optical fibers. The second optical fibers output the attenuated optical signal from the optical power attenuator to outside the housing. The optical splitter generates a split signal by splitting at least one of: the optical signal input to the optical power attenuator from the first optical fibers, and the attenuated optical signal propagated from the optical power attenuator to the second optical fibers. The optical power monitor receives the split signal and detects a power of the split signal.
