摘要： A WDM optical transmitter using a wideband gain laser comprises a plurality of wideband gain lasers and a wavelength division multiplexer. Each wideband gain laser includes a gain medium with a 3 dB bandwidth of 40 nm or more at a threshold current, and it amplifies corresponding incoherent light injected into the gain medium and outputs a corresponding channel. The multiplexer multiplexes channels, outputted from the wideband gain lasers, into an optical signal in a WDM scheme and outputs the multiplexed optical signal.

摘要： A method of growing a semiconductor layer in a selective area by Metal Organic Chemical Vapor Deposition (MOCVD) and a mask pattern for s ame, includes a first mask pattern and a second mask pattern that are formed on a semiconductor substrate having a (100) crystalline plane. The first mask pattern has a first window wider than the selective area and a second mask pattern has a second window and a third window. The second window is defined by spacing the second mask pattern from the first mask pattern, in correspondence with a blocking area for blocking the surface migration of III-group semiconductor source gases at edges of the first window. The third window is as wide as the selective area. The semiconductor layer is grown by MOCVD on the semiconductor substrate exposed by the second and third windows. Trenches can be etched in the second and third windows and growth layers extend from the trench beyond the surface of the InP to block gas dispersion.

摘要： Disclosed is a vibration module for a portable terminal that includes a housing, a magnetic moving part movable in a first direction within the housing; an elastic member supported between the opposite ends of the magnetic moving part and inner walls of the housing, and a solenoid coil provided in the housing. The vibration module is positioned at one end of the moving section by the magnetic force of the magnetic moving part and an object around the magnetic moving part, allowing the vibration module to provide a user with a feeling similar to a click feeling via the acceleration produced at a stopping instant. In addition, when vibrating, the vibration module generates sufficient vibration power through acceleration at the instant of changing moving direction at the ends of the moving section, to provide an alarm function, such as an incoming call notification.

摘要： Disclosed is a vibration motor for a portable terminal, including a flat spring; a cylindrical magnetic substance mounted on the flat spring; an annular magnetic substance disposed around the cylindrical magnetic substance mounted on the flat spring; and a coil disposed between the cylindrical magnetic substance and the annular magnetic substance, wherein the magnetic substances perform a linear reciprocal movement by the electromagnetic force generated between the magnetic substances and the coil and by the elastic force of the flat spring as an electric current is applied to the coil. The vibration motor operates at higher resonant frequencies than those of conventional vibration motors, thereby improving the sense of an after-vibration and realizing a delicate haptic feedback function.

摘要： An optical spot size converter integrated laser device includes a substrate; a first waveguide laminated on the substrate and optically coupled to an optical fiber, the first waveguide being divided into a light source region having an active waveguide and an optical spot size converter region, and a trench formed on both lateral walls of the first waveguide on the substrate so that light emitted from the active waveguide interferes with light reflected by a wall surface of the first waveguide inside the first waveguide. By means of mutual interference between light emitted directly from the active waveguide of the laser device and light reflected by the interference waveguide, the optical spot size of a laser can be adjusted without affecting the single mode of the laser.
