In this paper, a new technique for generation of ultra-wide and flattened optical frequency comb (OFC) based on serial cascading of a phase modulator and dual-driven Lithium-Niobate Mach Zehnder modulator (DD-LiNbO3-MZM) is proposed. Over 60 carriers

In this paper, a novel cost-effective optical multi-wavelength generation scheme based on a pulsed laser and a single Mach-Zehnder modulator (MZM) is proposed. Over 50 wavelengths has been achieved with the proposed cost-effective scheme among which

A novel technique is proposed for optical frequency comb generation with a budget friendly system. A Mach-Zehnder modulator is used in connectivity with continuous wave optical signal which is filtered by rectangle optical filter and the signal is th

In an optical multiple input multiple output (MIMO) transmission system, mode coupling and mode dispersion have a significant impact on the signal recovery processes at the receiver. We describe a polarization-based MIMO transmission by using mode di
