This manuscript presents optical frequency comb generation by employing two frequency modulators with dual drive MachZehnder modulator. The modulator FM1 is driven with radio frequency (RF) at 16 GHz, FM2 at 8 GHz and DD-MZM at 32 GHz respectively. These RF signals are directly driven by modulator without need a phase shifter. The generated optical comb produces 81 frequency comb lines with 0.2 dB to 1.5 dB maximum power deviation and having frequency spacing of 4 GHz with bandwidth 852 GHz. A theoretical study is carried out to examine the smooth spectrum produced by a sequences of frequency modulators and Mach-Zehnder with simulation results validate these findings provide substantial support for the observed results. The generated setup is power efficient as well as reliable. This setup design is applicable for optical communication, metrology and radio frequency photonics.

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.
