Wideband analog photonic links: some performance limits and considerations for multi-octave implementations

“…Balanced detection results in a similar expression without a DC component and with twice the RF current. Analysis of an analog link employing a Mach-Zehnder modulator (MZM) with direct detection [15] yields a result very similar to (4). The differences are that the MZI bias in (4) is replaced with the MZM bias and the Besselfunction arguments in (4) contain the frequency response of the MZI.…”

Analytical research is presented for electro-optic phase modulation followed by an asymmetric interferometer that is used for phase-to-intensity conversion. The resulting closed-form equations quantify the performance for arbitrary interferometer bias and input radio-frequency power. Even-order distortions, very important for multi-octave applications, are analyzed. Measured data for a Mach-Zehdner interferometer (MZI) are demonstrated to agree well with the theoretical results. Photodiode-induced even-order distortion is identified as the limiting nonlinearity when the MZI is biased at quadrature.

“…Another issue with MZM bias error is the generation of even-order distortion that is absent in an ideal quadrature-biased link. This can be seen in the form of (3) and is also detailed in [34]. Therefore, careful analysis must be conducted when considering such a wide bandwidth in multi-octave applications.…”
