Based on cascaded Mach-Zehnder Modulators (MZM), a novel scheme for optical generating of microwave frequency shift keying (FSK) signal is designed and demonstrated. In the designed scheme, a microwave FSK signal with frequencies of two and four times the frequency of driving microwave signal for bit ‘0’ and ‘1’ is generated. The feasibility of the designed scheme is verified by a simulation experiment. With 5 GHz driving microwave signal, a 1 Gbit/s microwave FSK signal at 10/20 GHz is generated and transmitted over 30 Km single-mode fiber (SMF).

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.
