摘要： An improved surface-emitting laser device by which the light emitting wave length can be easily varied since the electric potential grown using the thin film material having a desired lattice rate uses a very small portion of activation layers, and by which the continuous oscillation is made at room temperature by using the reflector having high reflective index. Thus, optical characteristics are increased, which includes a GaAs substrate; a lower reflector is formed of multiple layers of AlAs/GaAs heterogenous thin films having a reflective index of 1 on the GaAs substrate; a tooth-shaped grading layer is formed of a lower reflector on the lower reflector and an In.sub.x Ga.sub.1-x As thin film having a large lattice rate in a compositional grading method; a tooth-shaped InGaAs grading well is formed on the In.sub.x Ga.sub.1-x As grading layer as an In composition of which reduced rather than the grading layer; a buffer layer is formed on the In.sub.x Ga.sub.1-x As thin film and formed of a lattice-bonded InP; and an upper semiconductor reflector is formed on a multilayer of an InAlAs/InAlGaAs heterogenous thin film on the buffer layer, which has a reflective index of 1, in which a laser beam is emitted from the surface of the same.

摘要： A method for sensing the completion of removal of an oxide layer from a semiconductor substrate or a super conductor by a thermal etching in real time. In the method, the time of removal of the oxide layer on the semiconductor substrate or the super conductor can ben accurately sensed. According to the method, when an oxide layer which is different from the semiconductor substrate in the refractive index is being thermally etched at a high temperature, the reflected signals of the laser beams forms a periodicity, and this periodicity is utilized so as to determine the etching rate and the time of the completion of the etching.

摘要： A method of sensing the concentration of a doped impurity on a semiconductor in real time and a method of sensing the change of its growth rate dependent on time among the changes of the growing conditions due to doping by using a real time analysis apparatus in growing a heterostructured semiconductor by a MOCVD method. A reflecting signal during the growth by means of a real time analysis apparatus has a periodic property, an amplitude change of a reflecting signal is dependent on an absorption coefficient when an absorption exists on an epitaxial layer, an impurity concentration can be obtained by using the relation of an absorption coefficient and an impurity concentration. In addition, if each peak is independently analyzed, the respective growth rate dependent on time are measured individually, so that the reduced growth rate dependent on time of the growth rate is sensed in a carbon doped AlAs layer.

摘要： Provided is a self-oscillation communication module in which an optical device, a solar battery, and a radio frequency (RF) device are monolithic-integrated. When an active layer of the optical device contains In(Ga)As quantum dots, the optical device can emit light ranging from 800 to 1600 nm and transmit signals at a high speed of 20 Gbps or higher. Since a light absorption layer of the solar battery is formed of InGa(Al)P which has a higher bandgap than silicon and high visible light absorptivity, the solar battery can generate a large current even with a very small light reception area. Therefore, the self-oscillation communication module can always operate using the solar battery without an external power source even in polar regions and deserts and can perform optical communication or high-frequency wireless communication with a wide frequency range.
