The principal feature of the buried facet optical amplifiers relative to antireflective (AR -coated cleAR -coated devicleaveda polarization-independent reduction in mode refacetivity devicesthe burisd facet, resulting in better control in achieving polarization-independent gain.
Also shown is that of a 45° edge facet coupling device made from the same QCD wafer as the reference.
With normal incidence, significant enhancements of photocurrent response are obtained at the metamaterial resonances compared with the 45° edge facet coupling device.
According to the response spectrum obtained from the 45° edge facet coupling device, the dimensions of the metamaterial building block are determined and illustrated in the inset of Fig. 2.
In this paper, the effects of silicon recess geometry and SiGe step height on SiGe epitaxy growth, SiGe facet formation and device performance in a SiGe process-induced strained silicon device are investigated.
The major film studios perhaps view Facet as a device that could do to DVDs what the iPod did to recorded music.
To lower the mirror loss for short cavity DFB QCL, a partial-high-reflection (PHR) coating consisting of Al2O3/Ge was deposited on the front facet of the device by electron beam evaporation.
The most important facet of these devices won't be the sharpness of the display or the sleekness of the design — they will, after all, essentially be the same: flat pieces of glass of varying sizes.
Antireflection coatings of λ/4 were used on both facets of the device.
Granted, the Galaxy S design is under scrutiny due to its similarity to the iPhone 3G, but there are other facets of the device in question, as well.
