Null bias mach-zehnder interferometer with ring resonators
In Mach-Zehnder interferometer (MZI) based modulators (MZM) input laser light comes in from one side, gets split into two MZI arms, then recombined at an opposite side.

Ring resonator type modulators (RRM) are compact; however, their phase response is nonlinear, normally limiting their application in coherent phase modulation. However, a combined MZI RRM overcomes the shortcomings of the prior art by providing a novel structure and driving scheme for use with semiconductor photonics that takes advantage of the compactness of ring modulators and the linearity of MZI by setting the ring resonators to resonate at the input laser light wavelength. |

Disclosed herein is a ferritic steel having decreased specific gravity and having excellent mechanical strength by suppressing formation of κ-carbide. The ferrite steel may include: carbon (C) in an amount of about 0.05 to 0.12 wt %; aluminum (Al) in an amount of about 3.0 to 7.0 wt %; manganese (Mn) in an amount of about 0.5 wt % or less (not 0%); nickel (Ni) in an amount of about 0.5 wt % or less (not 0%); chromium (Cr) in an amount of about 0.75 wt % or less (not 0%); silicon (Si) in an amount of about 0.3 to 0.75 wt %; a combined amount of titanium (Ti) and vanadium (V) in an amount of about 0.25 to 0.7 wt %; and a balance being iron (Fe), all the wt % are based on the total weight of the ferritic steel. |

High strength aluminum alloy backing plate and methods of making
A method of forming a high strength aluminum alloy. The method comprises heating an aluminum material including scandium to a solutionizing temperature of the aluminum material such that scandium is dispersed throughout the aluminum material to form an aluminum alloy. The method further comprises extruding the aluminum alloy with equal channel angular extrusion to form a high strength aluminum alloy, such that the high strength aluminum alloy has a yield strength greater than about 40 ksi after being at a temperature from about 300° C. to about 400° C. for at least one hour. |

High-strength hot-dip galvanized steel sheet having excellent surface quality and spot weldability
Provided is a high-strength hot-dip galvanized steel sheet having good surface quality and spot weldability. The high-strength hot-dip galvanized steel sheet includes a base steel sheet and a zinc plating layer formed on the base steel sheet. The base steel sheet includes carbon (C): 0.1% to 0.3%, silicon (Si): 0.5% to 2.5%, manganese (Mn): 2.0% to 8.0%, soluble aluminum (sol.Al): 0.001% to 0.5%, phosphorus (P): 0.04% or less (excluding 0%), sulfur (S): 0.015% or less, nitrogen (N): 0.02% or less, chromium (Cr): 0.01% to 0.7%, titanium (Ti): (48/14)*[N] % to 0.1%, and a balance of iron (Fe) and inevitable impurities. The base steel sheet has a microstructure comprising ferrite in an area fraction of 5% to 30%, austenite in an area fraction of 5% to 20%, bainite and martensite in an area fraction of 50% to 80%, and precipitates in an area fraction of 2% or less. |
