Latest Patents

Goldstein's latest patents include a semiconductor optical component and a method of fabricating it. This invention discloses a semiconductor optical component that features a confinement layer containing acceptor dopants, specifically designed for p-type doping. The confinement layer is deposited on another semiconductor layer, defining a plane parallel to it. Notably, the p-type doping concentration of the confinement layer exhibits at least one gradient significantly different from zero in one direction within the plane.

Another significant patent is for a semiconductor optical amplifier. This invention involves an amplifier that includes at least two sections, each favoring a higher gain for the TE mode and the TM mode of polarization of the light being amplified. The sections possess an active guide structure of uniform thickness, but they are subjected to different tension stresses and/or have distinct geometries. This design ensures that the overall gain of the amplifier remains insensitive to the polarization of the light being amplified, with no discontinuity in the effective refractive index at the transition between the sections.
