Optically injected semiconductor laser under periodone oscillation is investigated as a source for photonic microwave transmission over fiber. The period-one nonlinear dynamics of an optically injected laser is studied for the purpose of minimizing the microwave power penalty induced by chromatic dispersion. Over a large range of injection strengths and frequency detunings, we first obtain the ...

Recently, coherent optical OFDM (CO-OFDM) has been proposed for optical networks to combat chromatic dispersion. CO-OFDM system has been successfully processed and recovered for transmitted signals without optical chromatic dispersion compensation. However, in optical links, the available optical power is limited due to fiber nonlinearity, and power consumption. As previously reported, we focus...

In this paper, we are interested on simulation tools developing for designing optical component based on Fiber Bragg Grating (FBG), with potential uses in optical communication systems and sensors. Both principals for understanding and techniques for synthesizing fiber granting are emphasized. We focus on the two major applications, which are the design of Encoders/Decoders for optical access n...

In this paper, we have proposed a novel structure of the fabrication of a chalcogenide As2Se3 glass photonic crystal fiber (PCF) with increased core diameter. As comparision with the normal PCFs in which silica glass is used as core material, the proposed PCF has following feature; firstly we have used the chalcogenide As2Se3 glass as core material in which the first ring area contains no air h...

A dispersive model of a gradient refractive index (GRIN) lens is introduced based on the idea of iso-dispersive contours. These contours have constant Abbe number and their shape is related to iso-indicial contours of the monochromatic geometry-invariant GRIN lens (GIGL) model. The chromatic GIGL model predicts the dispersion throughout the GRIN structure by using the dispersion curves of the s...

Optical correlation, or matched filtering, can now be applied more widely than before, because the light is now allowed to be totally incoherent, spatially and spectrally. Two such correlators were demonstrated recently. Their state of chromatic correction can be called achromatic, since the scaling error has two zero crossings within the visible range of wavelengths. We present a new apochroma...

The paper derives stationary optical solitons with nonlinear chromatic dispersion. A nonlocal form of nonlinearity and quintuple power–law are considered. Kudryashov’s integration scheme enables to retrieve such solitons. plethora come this algorithm.

We describe a demonstration of electrical chromatic dispersion compensation of 10 Gb/s single sideband optical signals. Eye-opening and bit error rates of less than 10 were achieved after compensation of -2040 ps/nm, equivalent to 120km of non-dispersion-shifted fibre and beyond the dispersion limit for 10Gb/s. A passive sideband filter was used to produce the single sideband signal, a techniqu...
