2011/5/4
Double quantum well (DQW) (In, Ga)(As, N)/GaAs p-i-n photodetectors, grown by solid source molecular beam epitaxy using a radio-frequency plasma source for nitrogen with absorption for wavelengths abo...
Method for estimating loss over wide wavelength region of fiber cables installed in access networks
Fiber characterization
2015/6/4
We propose a simple method for estimating the loss of installed cables to expand WDM access networks. Loss at arbitrary wavelengths can be very accurately predicted from the measured loss at a few wav...
