“…Nested MZM have also been widely used as a frequency shifter (FS) or single side band suppressed carrier (SSB-SC) modulator [128], [129], [130]. OFCs using a nested MZM as a FS have been rigorously investigated.…”

“…With an optical input at frequency ω, the field at the output should only consist of odd harmonics at the frequencies ω+nΩ, where n = (-1, 3, -5, 7 …). The amplitude of the sideband at frequency nΩ is described by the Bessel function J n (m), where m = π•U p /(2U π ) denotes the modulation index and U π is the π-voltage of the push-pull MZM [6].…”

“…Another approach is based on combining the output of two Mach Zehnder modulators (MZM) with a π/2 phase shift, hence realizing a device that acts independently on the in-phase and quadrature component of the optical signal. When driving the two MZM of such an IQ modulator by a sine and a cosine signal, frequency shifting by means of single side band (SSB) modulation can be achieved [5,6]. However, this concept suffers from a trade-off between SMSR and CE: For high SMSR, the MZM need to be driven in the small-signal regime, where the amplitude transmission depends linearly on the applied voltage.…”

“…In the high-extinction ratio lithium niobate (LiNbO 3 ) Mach-Zehnder intensity modulator (Izutsu et al (1977), Izutsu et al (1981), Kawanishi et al (2006), Kawanishi et al (2004a), Kawanishi et al (2004b), Kawanishi et al (2007), Onillon et al (2005), Vegas et al (2003)), the optical frequency difference between two optical signals is exactly twice (or four times) the modulation frequency, and the output signal is equivalent to FSK (frequency shift keying) spectrum. Compared to the optical phase lock scheme, the Mach-Zehnder modulator (shown in Fig.…”
