    • An optical device for coupling the light transmitted through an optical waveguide and a diffraction grating is provided to transmit the light of a single mode including a basic horizontal mode by supressing transmission of a second horizontal mode. An optical device is composed of an optical waveguide for transmitting a laser beam; a main diffraction grating(11) coupled with the wave-guided light transmitted through the waveguide; and a sub diffraction grating(12) coupled with the wave-guided light transmitted through the waveguide. The main and sub diffraction gratings are coupled with the wave-guided light so that an electric wave of a second horizontal mode of the wave-guided light is much more restricted if the main and sub diffraction gratings are arranged on both sides, in comparison with the electric wave generated if only the main diffraction grating is disposed.

    • PURPOSE: A method for fabricating a quantum hole is provided to fabricate a semiconductor light emitting device for generating light of a predetermined color by forming the quantum hole having a fine diameter of a nanometer size. CONSTITUTION: Ions are discharged from an ion gun(40) at a high speed. The discharged ions are focused to form an ion beam. The ion beam is vertically and horizontally deflected by using an injection deflecting unit(46,48) and is injected into a plurality of positions for forming the quantum hole of a semiconductor substrate(44) located in the front of the injection deflecting unit. The speed of the ion beam is controlled by an acceleration speed of the ion beam so that the ions of the ion beam is not injected into the semiconductor substrate because of the impact of the ion beam incident on the semiconductor substrate and the surface of the semiconductor substrate is physically eliminated. The time interval of incidence of the ion beam is set up to have a range in which a quantum hole of a single ion beam type is formed in the semiconductor substrate. The size of the ion beam is properly determined according to the size of the quantum hole and the ion beam is controlled according to the determination value to form the quantum hole.
    • 目的:提供一种制造量子孔的方法,通过形成具有纳米尺寸的微细直径的量子孔来制造用于产生预定颜色的光的半导体发光器件。 构成:离子枪高速排出离子枪(40)。 排出的离子被聚焦以形成离子束。 离子束通过使用注入偏转单元(46,48)而被垂直和水平地偏转,并被注入多个位置以形成位于注射偏转单元前面的半导体衬底(44)的量子孔。 离子束的速度由离子束的加速度控制,使得离子束的离子不会注入到半导体衬底中,因为入射到半导体衬底和半导体衬底上的离子束的冲击 衬底被物理清除。 离子束的入射时间间隔被设定为具有在半导体衬底中形成单个离子束型的量子孔的范围。 根据量子孔的尺寸适当确定离子束的尺寸,根据测定值控制离子束,形成量子孔。
