GaN films doped with Er were grown on (0001) sapphire substrates by radio-frequency plasma-assisted molecular molecular beam epitaxy (MBE).
THIS PAPER IS ELIGIBLE FOR THE STUDENT PAPER AWARD. Coded caching can significantly decrease the communication load in peak hours of the network.
We report the pump wavelength dependence of the gain of an erbium doped fiber amplifier pumped in the wavelength region 950 to 1000 nm.
Extended x-ray absorption fine structure measurements show that Er defects in O-poor Si closely resemble bulk Er sub 3 Si sub 5 with long ErBSi bonds, while in GaN, regardless of O content, Er subs
We will describe Er-doped aluminosilicate waveguide amplifiers integrated with 980nm/1550nm WDM on Silicon Optical Bench and report on their performance.
The sum-capacity for specific sub-classes of ergodic fading Gaussian two-user interference channels (IFCs) is developed under the assumption of perfect channel state information at all transmitters
In the Bell System Technical Journal, 56, No. 8 (October 1977), Figs. 2 and 3 on pp. 1454 and 1455 should appear as follows.
Fig. 14--Rate constant (fc) on log scale vs /T ( degree K ) for 5-5/8" X 5-7/8" X 1/4" thick PbSb grids. This is a plotting error only and does not alter the data nor the conclusions shown.
The factor exp [--iQ30 -- 0)z] appearing in equations (45), (53) and (54) should be replaced by this correct phase factor. All other equations remain valid.
