摘要： A semiconductor device in which a current is controlled by light includes a semiconductor member having a source unit and a drain unit and a channel unit through which electrons may flow between the source unit and the drain unit. The channel unit has a quantum well layer having a plurality of quantum energy levels and barrier layers provided adjacent to the well layer. Upon light irradiation of the quantum well layer, electrons make transitions between the different quantum energy levels, and the current flowing between the source unit and the drain unit is controlled by varying the mobility of these transitioned electrons.

摘要： In a polarization-state converting apparatus for use as an optical isolator, an optical modulator and the like, there are provided a waveguide including a magnetic semiconductor, a device for applying a magnetic field to the waveguide in a first predetermined direction, a device for applying an electric field to the waveguide in a second predetermined direction, and a mode conversion is caused via electrooptic and magnetooptic effects due to the electric and magnetic fields to change the polarization state of light propagating through the waveguide. When used as an optical isolator, the optical isolation is performed to compensate for degradation of the mode conversion rate due to a phase mismatch between light incident upon the waveguide and light emerging from the waveguide. When used as an optical modulator, the optical modulation of light emerging from the waveguide is performed by varying the electric field and an optical isolation function is effected while compensating for degradation of the mode conversion rate due to a phase mismatch between light incident upon the waveguide and light emerging from the waveguide.

摘要： An electron wave interference device controlled by a light is disclosed. The electron wave interference device includes a first channel to propagate an electron wave, a second channel arranged with an interval from the first channel for propagating an electron wave, and an magnetic field application device for applying a magnetic field into the first and second channels and a region sandwiched by those channels so as to traverse them. The electron waves which are respectively propagated in the first and second channels mutually interfere, and when the light is irradiated to those channels, a distance between peaks of wave functions of the electron waves which propagate in the channels is changed, so that a phase difference occurs in the electron waves.

摘要： There is provided a magnetooptic device including a substrate; a semiconductor layer having a quantum well structure formed on the substrate, in which the semiconductor layer is formed by alternately laminating a well layer and a barrier layer and at least the barrier layer in those layers contains magnetic ions; and electrodes to apply an electric field to the semiconductor layer. A light which was polarized in a predetermined direction is input to the semiconductor layer. A magnetic field is applied to the semiconductor layer. An electric field is applied to the semiconductor layer by the electrodes. The light which was transmitted in the semiconductor layer is extracted. A degree of leakage of a wave function of the carrier in the well layer into the barrier layer changes. An effective magnetic field which a carrier spin feels changes by an exchange interaction between the carrier spin and a magnetic moment associated with the magnetic ions. Thus, a degree of magnetooptic effect which is given to the transmission light changes. The degree of manetooptic effect can be controlled by the applied electric field. The magnetooptic device is preferably used as an optical modulator or an optical isolator in the field of optical communications or optical memories.

摘要： An electron wave interference device includes a source electrode for injecting electrons therethrough, a drain electrode for taking out electrons therethrough, channel means for propagating electrons from the source electrode to the drain electrode and a gate electrode provided on a halfway portion of the channel means between the source electrode and the drain electrode for dividing the channel means into plural channels solely in the halfway portion of the channel means. A positional relationship between the channel means and the gate electrode is set so that a depletion layer is extended under the gate electrode toward the channel means by applying a given voltage to the gate electrode. The depletion layer extended through the channel means forms an island which inhibits the propagation of electrons in the channel means and thus divides the channel means into the plural channels.
