英文摘要 | PURPOSE:To control an optical signal even if a signal in a substrate is very weak by controlling a large current applied to a light emitting diode by a weak signal current given to the base current of an integrated transistor. CONSTITUTION:A light emitting diode 20 such as a laser diode has a substrate 1, a current block layer 2, a lower clad layer 3, an active layer 4 and an upper clad layer 5. A transistor 30 has either one of a collector and an emitter commonly with the layer 5 of the diode 20, and has the other as a cap layer 6 and a base region 10 as a base. As a result, when a forward voltage of the diode 20 is applied to between the electrodes 8 and 9 and suitable control current is applied from an electrode 11, the forward voltage can be applied to the diode 20, and oscillation becomes possible. In this case, the transistor 30 amplifies the control current to control a large current flowing through the diode 20. |
