    Abstract: The present invention discloses an optical device including a quantum well structure having triple connections. The optical device may include the quantum well structure having triple connections which includes three asymmetric quantum wells connected to each other through two connection walls having a lower energy level compared to a common wall. In the quantum well structure having triple connections, when voltages are applied to the optical device, much of the wave function of holes and electrons are distributed in the quantum wells in the center to be overlapped via an energy controlling function of the two connection walls. Therefore, increased thickness of a quantum well layer can not only reduce driving voltages of the optical device but also maintain an overlapped state of the wave function of holes and electrons to be enough. Therefore, absorption intensity can be increased.

    Abstract: PURPOSE: A 3D image obtaining device and a depth information calculation method in the 3D image obtaining device are provided to synchronize light projection time and driving time of a light modulator, thereby obtaining reflective light which external light is removed. CONSTITUTION: A light modulator(103) modulates light reflected from a subject(200) by the number of projected N light. A photographing device(105) generates the number of N sub-images by photographing the modulated light. A signal processing unit(106) calculates depth information for distance with the subject by using the sub-images. A control unit(107) synchronizes exposure time of the photographing device with driving time of the light modulator.
