“…j 0 is proportional to laser-emitted power and suggests that operation at low laser powers (low bias) is more vulnerable to noise, Downloaded by [Northeastern University] at 13:03 20 November 2014 as expected. The noise has a resonant behavior due to the involvement of the IM transfer function inŝ ω ,ν ω , andˆ ω as explained in Yabre [4]. A low FSR is required for good signal linearity in PM to IM conversion [4], creating a tradeoff between linearity and noise.…”

“…The noise has a resonant behavior due to the involvement of the IM transfer function inŝ ω ,ν ω , andˆ ω as explained in Yabre [4]. A low FSR is required for good signal linearity in PM to IM conversion [4], creating a tradeoff between linearity and noise. For the wavelength converter, the choice of FSR would depend on the magnitude of phase or frequency modulation induced on the converter laser through XPM, a parameter that is well under the control of the system designer by varying the laser power and SMF length.…”

“…Following the analysis in Yabre [4], the total noise spectrum of the laser after passing through the MZI is defined by the relative output noise RON(ω) = |p ω | 2 /p 2 o where the numerator denotes the power spectral density of the output intensity fluctuations and p o is the converted signal output power. It is a summation of three terms; the classical RIN, a term proportional to the power spectral density (psd) of the frequency noise and a term resulting from the cross correlation between the two noise sources and is given by…”

“…The performance of the wavelength converter and its optimum operating points has been studied by Sarker et al [3], but the noise of the device was not studied in detail. We refer to the model used by Yabre [4] to analyze the noise induced by the laser used in the wavelength converter. Then, we extend the analysis to examine the impact of the noise on a typical direct-detection link found in most WDM networks.…”

The overall intensity noise spectrum due to laser relative intensity noise (RIN) and interferometric conversion of laser phase noise after passing through wavelength conversion (WC) based on cross-phase modulation (XPM) and Mach-Zehnder interferometer (MZI) is modeled along with the resulting noise at the direct-detection receiver. It is found that the effect of the laser-induced noise at the receiver is negligible when the MZI operated at quadrature and has a free spectral range (FSR) > 0.01 GHz. Only when FSR < 0.01 GHz is a power penalty induced that increases with decreasing laser current bias, j 0 (0.8 dB, j 0 = 2; 1.7 dB, j 0 = 1.5; 5.2 dB, j 0 = 1.1).

Performance analysis is carried out to investigate the effect of amplified spontaneous emission (ASE) noise, interferometric intensity noise from wavelength converter and crosstalk due to WDM components on the performance of an optical multi-wavelength transport network employing wavelength converters based on XPM in a single-mode fiber (SMF) and Mach-Zehnder interferometer (MZI). The results show an accumulation of noise from the ASE and wavelength converter as a channel traverses through N OXCs resulting in a receiver sensitivity of -20.0 dBm for N = 5 and -13.1 dBm for N = 20. The ASE noise is dominant at the receiver as the interferometric intensity noise is insignificant by comparison. The accumulated interferometric noise at the receiver depends on the Free Spectral Range (FSR) of the MZI used. With ASE ignored, it produces significant noise with small values of FSR (< 0.01 GHz).

Photonic systems that transmit and process microwave-frequency analog signals have traditionally been encumbered by relatively large signal distortion and noise. Optical phase modulation (PM) and frequency modulation (FM) are promising techniques that can improve system performance. In this dissertation, I discuss an optical filtering approach to demodulation of PM and FM signals, which does not rely on high frequency electronics, and which scales in linearity with increasing photonic integration. I present an analytical model, filter designs and simulations, and experimental results using planar lightwave circuit (PLC) filters and FM distributed Bragg reflector (DBR) lasers. The linearity of the PM and FM photonic links exceed that of the current state-of-the-art.
