摘要： An optical operator designed to be subjected to write radiation for processing read radiation that it receives, the operator comprising an electro-optical material (Q2), first and second materials (Q1, Q3) distributed on either side of the electro-optical material (Q2), said first and second materials (Q1, Q3) being collection quantum wells. Quantum barrier forming materials (6, 8) are interposed between said two materials (Q1, Q3) and the electro-optical material (Q2), with one of the quantum barrier forming materials (6) constituting a filter such that charges of a certain sign photoexcited by the write radiation in a material (4, Q1) on one side of said filter pass through it in the absence of an external electric field to relax in the collection quantum well (Q3) situated on the other side of the filter (6), while charges of opposite sign are blocked by the filter (6) in the other collection well (Q1).

摘要： Optical semiconductor device with resonant cavity tunable in wavelength, application to modulation of light intensity. This device comprises a resonant cavity (2) delimited by two mirrors (4, 6) and at least one super-lattice (14) that is placed in the cavity and is formed from piezoelectric semiconducting layers, and means (20) of injecting charge carriers into the super-lattice. The optical properties of this super-lattice can thus be modified and the wavelength of cavity resonance modes can be offset. The invention is particularly applicable to optical telecommunications.

摘要： Semiconductor laser with a tunable gain spectrum. Said laser comprises an active zone having at least one active quantum well (AQW), which emits a laser radiation during the introduction of carriers into the active zone and at least one collection quantum well (CQW1, CQW2) on either side of the active well, for collecting and confining part of the carriers introduced. Means for distributing carriers in the collection wells are provided for creating a space charge field for modifying, during the emission of radiation and by an electrooptical effect, the gain spectrum of said active well. Application to optical telecommunications.
