gain in the for the optical fiber communication applications interesting 1.5-mum region were only conducted about two years ago, there is reason to believe that substantial progress may be made in the future, perhaps involving "holey fibers" to further enhance the nonlinearity and thus the gain....
The fabricated amplifiers had a maximum bandwidth of 19 GHz and an associated transimpedance gain of 47 dBΩ. The large signal characteristics of two transimpedance amplifier designs with similar gain were also investigated and showed that the cascode approach is much less sensitive to input power ...

The authors review recent advances in SOAs (semiconductor optical amplifiers) and some of their applications. SOAs are under rapid development to achieve polarization independent gain, low facet reflectivities, good coupling to optical fibers, and high saturation power. The package SOA can be made ...

Infrared Fibers and Their Applications As an expert in the field with nearly 30 years' experience, Harrington provides complete and up-to-date coverage of infrared fiber technology. Readers are given in-depth facts about the three key types of IR fibers, including how they de... Harrington,Jam...
Galectins and their ligands: amplifiers, silencers or tuners of the inflammatory response? Recent evidence has implicated galectins and their ligands as master regulators of immune cell homeostasis. Whereas some members of this family, such as ga... Gabriel,A,Rabinovich,... - 《Trends in Immuno...
A multiwavelength, multistage optical amplifier, which can be arranged in a cascade, substantially increases the degree of automatic power control (APC), multiwavelength APC (MAPC), and multiwavelength automatic gain control (MAGC), for at least two wavelengths. The multiwavelength, multistage optical...
The amplified signal/idler pulses passed through a long-pass filter to suppress the 800 nm pump, and their spectra were measured with a thermoelectrically cooled InGaAs array detector (Ocean Optics NIR256-2.5). The signal/idler, as well as pump beam power values were measured with a ...
Because comparators are rarely configured with negative feedback, their (differential) input impedance is not multiplied by loop gain, as is characteristic of op amp circuits. As a result, the input signal sees a changing load and changing (small) input current as the comparator switches. Therefo...
