    Abstract: A drive circuit includes a first transistor that is controlled to be in on or off state in response to a control signal, and outputs, in on state, a positive current which is input from a first operational amplifier connected with a drain of the first transistor to a semiconductor optical amplifier; and a second transistor that is connected with a source of the first transistor, and is in inverse on or off state to the state of the first transistor. The drive circuit also includes a negative voltage circuit that is connected to a source of the second transistor, and outputs, when the second transistor is in on state, a negative current to the semiconductor optical amplifier.

    Abstract: In an optical unit having a holding structure which brings a junk ring or the like into contact with an optical surface of a lens, the optical surface suffers from a serious elastic deformation leading to deterioration of optical performance. Upon holding the lens, therefore, a face other than the optical surface is provided on the lens so that the lens is held by applying a force to the face from element holding members.
