“…In this paper, we assume Lorentzian lineshape for both lasers [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]. Assumption of the Lorentzian lineshape is equivalent to the assumption of the white frequency fluctuations spectra [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16]: rad 2 Hz = rad 2 · Hzl for -oo<f<oo (2) where Φ [rad/s] is the instanteneous angular frequency deviation, S<j,(f) is the two-sided power spectral density of Φ, and the parameter W [Hz] is related to the 3 dB laser linewidth Δ ν by the following expression:…”

“…A recent interest in optical coherent detection techniques [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] was stimulated by the progress in semiconductor laser and single-mode fiber technologies, and by the promise of higher receiver sensitivity, of larger repeaterless range, and of improved network capabilities. Thus, a considerable effort has been devoted to heterodyne systems research [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15].…”

“…Thus, a considerable effort has been devoted to heterodyne systems research [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15]. It is clear now that the laser phase noise is a major problem in heterodyne communication systems: it broadens the laser linewidth and deteriorates the performance of heterodyne receivers.…”

The impact of laser phase noise on optical heterodyne communications receivers is analyzed in terms of the system signal-to-noise ratios and error rates. An ASK receiver, three FSK receivers and a DPSK receiver are investigated. The maximum permissible laser linewidth Δν is evaluated for each of these receivers and compared with previously published theoretical and experimental results. It is shown that Δν depends on the system data rate R and on the modulation/demodulation technique chosen. For example, DPSK receivers require at least Δν ^ 0.7% of R while FSK receivers with postdetection frequency discrimination require at least Δν ^ 1.9% of R if the mark-space separation 2 f d is equal to R. At the same time, ASK receivers with envelope postdetection processing, and FSK receivers with large frequency deviation are much more tolerant to phase noise: they only require Av<9%ofR.

“…Thus, both Type (b) and Type (c) optical heterodyne detection systems can be used for local distribution, metropolitan area network (MAN), or multichannel short links. Since details of this electrical demultiplexing by 0 : PERIODIC FILTER optical heterodyne have been examined in other papers [7], 1'151, [16], this paper will mainly focus on optical filtering.…”
