Commercial high-speed silicon (Si) Mach-Zehnder modulator (MZM) required to be active around the quadrature bias point (linear transmission area) with low power consumption, small footprint, and small drive voltage. The bias controlling is done by an optical phase-shifter (PS). However, the ...
This sets the bias level on the baseband amplifiers to VREF, which is equal to approximately 1 V. Alternatively, with LK11 removed, the bias level of the baseband amplifiers can be set by applying an external voltage to the VCMO test point. C8, C9, R4, R5 Baseband amplifier outputs and...
“Signal Generator” is the ideal case where the LO is generated using a Rhode & Schwarz signal generator with a sinusoidal output and much lower harmonic levels compared to the ADF4350. This is the ideal case and the target comparison point. From Figure 5, it can be seen that filtering ...
Compared with the EKF, the point-based methods have two important advantages: (1) derivative free and (2) achieving higher order approximation to nonlinear functions. All the Gaussian approximation filters involve using numerical quadratures to approximate the expectations of nonlinear functions with ...
quadrature bias point marked on the curve. As discussed previously, a bias compression function can be applied to an optical modulator to expand the top level of an optical signal (e.g. PAM-4) by compressing the bottom level. It is important to note that in biasing the optical modulator ...
