Simultaneous four-wave mixing and cross-gain modulation for implementing an all-optical XNOR logic gate using a single SOA

Cross Phase Modulation and Four - Wave Mixing

All-optical modulation of four-wave mixing in an Rb-filled photonic bandgap fiber.

We demonstrate efficient all-optical modulation using Rb vapor confined to a hollow-core photonic bandgap fiber. The intensity of a signal field participating in the four-wave-mixing process is modulated using a weak switching field. We observe 3 dB of attenuation in the signal field with only 3600 photons of switching energy, corresponding to 23 photons per atomic cross section lambda(2)/(2pi)...

Optical Wavelength Converters Based on Cross Gain Modulation and Cross Phase Modulation in Soa

All optical wavelength conversion is demonstrated at 10 Gbit/s over a wavelength span of 10 nm without any bit loss by the use of Semiconductor Optical Amplifier (SOA) in a Mach-Zehnder configuration. These wavelength conversion architectures are implemented by using SOA cross-gain modulation (XGM) and cross-phase modulation (XPM) techniques. We have compared the results of both techniques on t...

All-optical multicasting NOT and NOR logic gates using gain modulation in an FP-LD

We demonstrate all-optical NOT and NOR logic gates at 10Gb/s based on gain modulation of a transverse electric (TE) polarized light in a Fabry-Perot laser diode (FP-LD). An FP-LD shows a gain for a TE-polarized injected probe beam. The gain can be modulated by injection of a pump beam. Using the gain-modulation characteristic, we implemented all-optical NOT and NOR logic gates. We investigate d...
