... probe pulse propagates slowly; (2) the prediction that superradiance has a dependence on the sign of the detuning of the pump laser due to a phase-matching condition. The theory of Raman (or Rayleigh) amplifiers is well known. For the situation of matter-wave superradiance in a Bose-Einstein condens ...

All-optical High Speed Logic Gates Using SOA
... control beams are sent into port A and B of the gate. The wavelengths of the two input signals can be same or different. Input signals from A and B enter the first coupler and combine with CW in second coupler. These combined waves then enter the SOA. Existence or non existence of data stream A and ...

Since far above resonances, nonlinearities decrease with frequency, and since highly brilliant sources in the x-ray portion of the electromagnetic spectr ...

Radio telescopes do not have a lens to focus the shorter wavelengths of light, but instead use a parabolic shaped dish or reflector to collect and reflect the longer radio waves or power toward a subreflector situated close to the prime focus which directs the radiation to ...

... sun emits all its energy at 1.3 µm, How much attenuation in decibels do you need to reduce the sun's entire output to a single 1.3-µm photon per second? Answer: The ratio is 2.375 x 1045, which corresponds to 454 dB. 4. If an entire galaxy contains a billion stars, each one as luminous as the sun, h ...

... •They can produce severe crosstalk when multiple optical channels are amplified. This latter characteristic makes them unusable as amplifiers in WDM systems but gives them the ability to act as wavelength changers and as simple logic gates in optical network systems. A major advantage of SOAs is tha ...
