    摘要: Opto-electronic light emitting device (30) epitaxially grown in III-V technology. It consists of a light emitting element (10), such as a diode laser or a LED, arranged back-to-back on a pn-junction diode (35), e.g., a PIN diode structure. A common middle layer (33) is transparent for the emitted wavelength and allows strong optical coupling (of at least 50 %) of the spontaneous isotropic radiation emitted by the light emitting element (10) to the diode (35) where the light is absorbed and recuperated for feedback to the light emitting element. The diode can be operated either as a photodiode or as a solar cell (by applying either a reverse- or a forward-bias voltage) resulting in regaining of either current or energy.

    摘要: The erasable electro-optic storage disk for use in focused laser beam operated data handling systems compri­ses a semiconductor substrate (11) with a storage layer (14) arranged on top of it that is capable of trapping charge carriers. Electric contacts (15, 16) are connected to the semiconductor substrate and to the storage layer, respectively. An energy barrier (12-13) with associated depletion zone is formed in the substrate (11) near the interface with the storage layer (14). Upon simultaneous application of a control voltage to the contacts (15, 16) and of a focused laser beam (18) directed at a storage site (19), electron pairs are generated in the depletion zone, and charge carriers are transferred towards the interface. This causes a reduction of the depletion zone and thus of the voltage over the depletion zone, and an increase of the field in the storage layer (14), whereby charge carriers are injected into and trapped in the storage layer (14).
