    Abstract: A light-emitting element driving circuit includes a drive transistor having a first terminal receiving a power supply voltage, a second terminal coupled to an anode of a light-emitting element, and a control terminal receiving an input signal, the drive transistor supplying a pulse current and a first bias current to the light-emitting element. A constant-current source is coupled to the anode of the light-emitting element and supplies a second bias current to the light-emitting element. A compensation circuit controls the second bias current so that a variation in the first bias current due to a temperature variation can be compensated for thereby the sum of the first and second bias currents is kept constant.

    Abstract: An integrated semiconductor laser array apparatus which is simple in structure and yet capable of stabilizing the light output from each individual semiconductor laser element. The integrated semiconductor laser array apparatus includes a semiconductor laser array provided by integrating a plurality of semiconductor laser elements. The semiconductor laser array includes a master semiconductor laser element selected from the plurality of semiconductor laser elements and slave semiconductor laser elements constituted of the remaining semiconductor laser elements. A laser beam output from the master semiconductor laser element is sensed by a photodiode and thereby a photocurrent corresponding to the received light ,intensity is generated and the bias current for the master semiconductor laser element is controlled by a first bias current control circuit such that the generated photocurrent is kept constant. The bias current for each of the slave semiconductor laser elements is controlled by a second bias current control circuit depending on the output from the First bias current control circuit such that the ratio between the bias current for the master semiconductor laser element, and the bias current for each of the plurality of slave semiconductor laser elements is kept constant.

    Abstract: An optical drop-and-insert apparatus which can process an optical signal in the form of an optical signal without converting the optical signal into an electric signal. The optical drop-and-insert apparatus expands the pulse width of an optical data pulse in an optical data pulse train on an optical highway and drops the optical data pulse to form an empty bit at the bit of the optical data pulse or another bit so that a new optical data pulse may be inserted into the empty bit. Miniaturization of the apparatus and increase in processing speed can be attained by enabling processing of an optical signal while it remains in the form of an optical signal.
