A high-temperature characteristics of 1.52 μm InGaAs ridge waveguide laser diode (LD) with InGaAs/InAlAs short period superlattices (SPSs) barriers is reported. The SPSs are grown by digital-alloy molecular beam epitaxy (MBE). There have been similar studies at the 0.98 μm LD using GaAs/AlGaAs SPSs barrier (T0=300 K) and 1.3 μm InGaAsP LD using (InGaAsP)4/(InP)5 SPSs barrier (T0=90 K). On the ...


Microlens-integrated vertical-cavity surface-emitting lasers for large-tolerant fiber optic coupling

ICTON Mediterranean Winter Conference, 2007. ICTON-MW 2007, 2007

We have fabricated microlens-integrated vertical-cavity surface-emitting lasers (VCSELs) by selective oxidation of composition-graded digital alloy AlGaAs. Microlens-integrated VCSELs with self-aligned structure was fabricated using standard VCSEL processing without additional process steps, due to the simultaneous formation of a microlens and oxide aperture. The output beam from the oxide-buried and oxide-removed AlGaAs microlens-integrated VCSELs has a beam radius of 3.7 mum ...


Proposal of ZnSe/GaAs digital alloys for high band gap solar cells and true green LEDs

Nanotechnology Materials and Devices Conference, 2009. NMDC '09. IEEE, 2009

Solar cells tuned for high energy photon absorption and light emitting diodes tuned for true green wavelength emission are proposed using the ZnSe/GaAs (001) superlattice. The effective band gap of this superlattice as a function of monolayers of ZnSe and GaAs within the range of 1.5 to 2.3 eV is shown. A discussion is given on the application of this ...

This paper explores some aspects of the erasure of signals from magnetic recording media. The first part gives the erasure characteristics for several different types of materials in current use for magnetic recording. A novel method of displaying the results shows that γ-Fe2O3and Cobaloy metal alloy particles behave substantially the same, while CrO2and Co-doped gamma ferric oxide are different from ...

Electrical characterization and modeling of simultaneous switching noise for leadframe packages

M. Miura; N. Hirano; Y. Hiruta; T. Sudo 1995 Proceedings. 45th Electronic Components and Technology Conference, 1995

Quad-flat packages with a leadframe made of copper (Cu), or alloy 42 are widely used for CMOS digital applications. As the clock speed of CMOS VLSIs increases, the package inductance is considered to be a limiting factor for their performance. To investigate the relationship between package inductance and switching noise, three types of leadframe materials, Cu, alloy 42, and Ag- ...
