Based on parallel Mach-Zehnder Modulators (PMZM), an optimized scheme for improving the generation of frequency quadrupling photonic millimeter-wave is proposed. In the designed scheme, by optimizing unbalanced modulation indices of each MZM, high-quality photonic millimeter-wave was still generated under non-ideal actual MZM condition. The feasibility of the proposed scheme is verified by theoretical analysis and simulation experiment. With the proposed approach, both the optical sideband suppression ratio (OSSR) and RF spurious suppression ratio (RSSR) of the generated photonic millimeter-wave have been enhanced, and the receiver sensitivity of the corresponding Radio over Fiber (RoF) transmission system has also been optimized.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
