“…For 2-channel system with . As a result, the left FWM product is the larger one for any frequency spacing due to 2 1 P P  , see [9]. The situation is changed for comparable 1 P and 2 P , where the saturation effects will dominate at the higher frequency.…”

“…Similarly, two photons at the frequency w 2 are annihilated to create two photons at the frequency at w 2 – Ω and w 2 + Ω. As a result, the left FWM product is the larger one for any frequency spacing due to P 1 >> P 2 , see [9]. The situation is changed for comparable P 1 and P 2 , where the saturation effects will dominate at the higher frequency.…”

“…In multichannel fiber-optic communication systems using wavelength division multiplexing (WDM) system [6]–[8], FWM gives rise to interference between channels, thus decreasing the channel quality. Impairments due to FWM play a role in pseudo-linear transmission systems [9,9] as well as in parametric amplifiers. FWM products are of particular importance, as those products fall into the signal band.…”

“…The determination of FWM products number is a classical problem, but the calculation of each power generated at a certain frequency is very important subject. WDM promises advantages for switching and routing as well as for transmission [9,9]. Optical cross-connects are currently being developed which can switch an entire wavelength from an input fiber to an output fiber.…”

In this paper, a generalized equation of pulse propagation in semiconductor optical amplifier (SOA) under the effects of four wave mixing (FWM) has been derived. This equation is applicable for any wavelength division multiplexing system in presence of both interband and intraband effects. The equation is solved numerically regarding the primary conditions of the problem considering the amplitudes of the sideband pulses at the entrance of SOA are zero. The gain of low frequency pulses will be higher than the gain of the high frequency pulses, as well as the gain difference between different pulses will be reduced with the increasing of frequency detuning. On the other hand, the effects of saturation and the asymmetric gain will control the mixing efficiency of the sideband pulses generated on the left and right of active pulses depending on the power of the input pulses and the frequency detuning.

“…FWM or phaise conjugation in both optical fibers and semiconductor optical amplifiers is investigated from several points of view [ 151- [20], which includes dispersion compensation methods and channel crosstalk analysis of multiwavelength transmission systems [21]- [25]. Successful operation in phase noise cancellation [26], dernultiplexing [2'7]- [29], and spectral inversion for fiber chromatic dispersion compensation [30] using semiconductor amplifiers were reported, and high conversion efficiency was also indicated in [?IO].…”

A new phase lock loop (PLL) is proposed and demonstrated for clock recovery from an ultrahigh-speed time-division multiplexed (TDM) optical signal. A traveling-wave laser-diode amplifier (TW-LDA) is used as a phase detector, and the crosscorrelation component between the optical signal and an optical clock pulse train is detected as a four-wave-mixing (FWM) signal generated in the T W-LDA. A timing clock from a TDM signal is extracted as a prescaled electrical clock, and this prescaled clock is directly recovered from a randomly modulated TDM optical signal. A prescaled 6.3 GHz clock is successfully extracted from a 100 Gb/s signal using the timing comparison output obtained as the cross-correlation between the optical signal and a short ( 4 0 ps) 6.3 GHz optical clock pulse train in the generated FWM light. A comparison of tlhe PLL phase noise with a previously reported gain modulation method is also shown, and the possibility of the Tbit/s operation of this PLL is also considered in the experiments.
