    摘要: A stepper system for ultra-high resolution nano-lithography employs a photolithographic mask which includes a layer of an electrically conductive optically opaque material in which periodic arrays of sub-wavelength apertures are formed. The plasmonic excitation in the photolithographic mask exposed to the light of the wavelength in the range of 197 nm-248 nm, produces high resolution far-field radiation patterns of sufficient intensity to expose a photoresist on a wafer. The stepper system demonstrates the resiliency to the mask defects and ability to imprint coherent clear features of nano dimensions (45 nm-500 nm) and various shapes on the wafers for integrated circuits design. The stepper system may be adjusted to image the plane of the highest plasmonic field exiting the mask.

    摘要: A nanophotolithography mask includes a layer of an electrically conductive optically opaque material deposited on a mask substrate in which regular arrays of sub-wavelength apertures are formed. The plasmonic excitation in the layer perforated with the sub-wavelength apertures arrays under the light incident on the mask produces high resolution far-field radiation patterns of sufficient intensity to expose a photoresist on a wafer when propagated to the same. The fill-factor of the mask, i.e., the ratio of the total apertures area to the total mask area, may lead to a significant increase in mask manufacturing throughput by FIB or electron beam “writing”. The mask demonstrates the defect resiliency and ability to imprint coherent clear features of nano dimensions and shapes on the wafers for integrated circuits design.

    摘要: A semiconductor optical amplifier (SOA) with efficient current injection is described. Injection current density is controlled to be higher in some areas and lower in others to provide, e.g., improved saturation power and/or noise figure. Controlled injection current can be accomplished by varying the resistivity of the current injection electrode. This, in turn, can be accomplished by patterning openings in the dielectric layer above the current injection metallization in a manner which varies the series resistance along the length of the device.

    摘要: A cavity-less vertical semiconductor optical amplifier is provided which includes an active region of an intrinsic bulk semiconductor material sandwiched between p- and n-layers of semiconductor materials in which a vertical gain channel of a predetermined confined cross-sectional configuration is formed to constitute an amplification region of the optical amplifier. The amplification region is sandwiched between layers of p- and n-doped layers of linearly graded semiconductor material supplying holes and electrons to the active region upon switching “ON” of the optical amplifier. Several factors contribute to substantial amplification of an optical signal at a relatively low injection current which include a relatively long active region allowing sufficient single pass gain as well as a strictly confined cross-sectional configuration of the vertical gain channel which reduces the active volume of the amplification region resulting in substantially high gain at a relatively low current. Flattening of the conduction band and valence band profiles allows easy access of the holes and electrons into the active region. The cavity-less vertical semiconductor optical amplifier of the present invention is intended for multidimensional architectural structures for high speed communication.
