Demonstration of Broad and Flat Optical Frequency Comb Generator by Employing Highly Non Linear Optical Fiber

The optical frequency comb (OFC) is prospective technique that can hike up the communication carrying capability of wide range in optical fiber communication [1]. Due to its numerous applications, including ultra-short pulse generation for different wavelength [2] multi-wavelength ultra-fast photonic signal processing, high-accuracy optoelectronic detectors and wavelength division multiplexing [3, 4], it draws attention of researchers. A collection of spectral lines is produced by a continuous laser source modulating a radio frequency signal. This manuscript proposed an effective technique for generation of OFC with cascading of modulators with Highly Nonlinear Fiber (HNLF) that produces coherent and highly spectral comb lines.
