摘要： An active semiconductor device that performs in a substantially polarization independent manner. A quantum well waveguide is intermixed by intermixing atoms across an interface between well and barrier layers. The atoms include at least 2 groups wherein intermixing of one group is at a substantially greater rate than another group. Cations are interdiffused at a greater rate than said anions across interfaces between well and barrier layers. The intermixing must be sufficient to provide strain within layers of the waveguide and sufficient to at least partially degenerate light hole and heavy hole bands of the structure. Preferably intermixing is sufficient to completely degenerate light hole and heavy hold bands to essentially produce a device that is completely polarization independent.

摘要： In a method of bandgap tuning of a quantum well heterostructure wherein ions are implanted in the heterostructure by ion implantation, the ions are implanted so that different regions are implanted in such a way as to create different concentrations of defects. This provides varying bandgap energies to various areas of the heterostructure during a subsequent thermal treatment, which removes residual defects and initiates intermixing in the quantum well region to result in a structure having a selectively shifted bandgap.

摘要： A method of selectively tuning the bandedge of a semiconductor heterostructure includes repeatedly forming a disordered region that is spatially separated from a quantum well active region and subsequently annealing the heterostructure each time after the disordered region is formed, so that vacancies/defects in the disordered region diffuse into the quantum well region and enhance interdiffusion at the well-barrier heterojunctions. Repeating, the disordering followed by annealing allows for a greater range in bandgap tuning. The heterostuctures of interest are IH-V material systems, such as AlGaAs/GaAs, where the active region includes structures such as a single quantum well, a multiple quantum well, or a superlattice.

摘要： A method of fabricating a semiconductor heterostructure includes the growth of a quantum well active region that is highly lattice-mismatched relative to a substrate. A buffer layer having a thickness above a critical value is grown on the substrate whereby the stress due to a lattice constant mismatch between the buffer layer and substrate is relieved through the formation of misfit dislocations. A strained superlattice structure is grown on the buffer layer in order to terminate any upwardly-propagating dislocations. An unstrained barrier layer is subsequently grown on the superlattice structure. The fabrication method concludes with the growth of a quantum well structure on the unstrained layer wherein a lattice constant mismatch between the quantum well structure and the unstrained barrier layer is smaller than the lattice constant mismatch between the quantum well structure and the substrate. As a result, only a fraction of the stress due to the large lattice mismatch between the quantum well structure and the substrate is accommodated by coherent strain in the quantum well structure, while the remainder of the stress is relieved through the formation of misfit dislocations spatially separated from the quantum well structure.

摘要： The present invention relates to a semiconductor optical amplifier system integrated within a semiconductor waveguide structure. The semiconductor optical amplifier system comprises a first semiconductor optical amplifier having a first spectral response and a second semiconductor optical amplifier having a second other spectral response. The second semiconductor optical amplifier is coupled to the first semiconductor optical amplifier for optically receiving an amplified optical signal from the first semiconductor optical amplifier. The center wavelengths of the first and the second spectral response are selected such that an optical signal provided to the first semiconductor optical amplifier and amplified thereby and then provided to the second semiconductor optical amplifier and amplified thereby is amplified approximately a same amount across a band of wavelengths larger than the band of wavelengths across which the optical signal was amplified approximately consistently by the first semiconductor optical amplifier alone.
