“…Firstly, the system design via (1) -( 12) by using the programming is transformed in GUI. The system designer can insert the value for generating the input signal of any frequency and after that from just signal click the signal will be converted in digital domain [29][30]. The next tag is used for converting optical signal from electrical one via modulation.…”

Chromatic Dispersion (CD) is the important effect that is considering for optical communication system design as it broadens the pulse during the propagation along channel resulting in pulse overlapping and ultimately bit errors raises. The increment in bit error, in result reduce the performance of optical system. Therefore, mitigation CD is necessary in order to improve the performance of optical communication system. There are several techniques of mitigating CD have been proposed and all based on coding based and this will create issues for the communication design engineer that every time the parameters need to be revised. In order to avoid this issue, the ease for the system design engineer has been created in designing the Graphical User Interface (GUI). In this work, GUI is designed and developed that will request the parameters need to be select for the optical system and it will describe the all process for mitigating it from the system. In the first, the communication system designer have to select the Transmission along with modulation and after that transmission at distance is asked in terms of km. The CD is mitigated uses least mean square technique and Fast Fourier Transform method. The further smoothing of signal is improved by Pulse shaping via using the raised cosine filter. In the end, the original signal and the compensated signal are defined. The BER is also calculated to show whether the reduction through DSP is performed. The GUI is developed in MATLAB and every button backhand the strong coding is used in C++ for developing the system. The designed and developed system offers the ease of use for the communication engineer, in which on one platform the user can observer well the optical system instead of programming.

The microwave photonic (MWP) beamforming chip is a crucial component for achieving the miniaturization of optically controlled phased array radar systems. It addresses the unwanted ‘beam squint’ effect of traditional electronic antenna arrays in processing wideband RF signals through optical tunable delay lines (OTDLs), which has garnered significant attention and research efforts in recent years. This review provides a comprehensive overview of the latest research progress on the classification, working principle, calibration and delay measurement methods, driving and control technologies, and system function verifications of OTDL and MWP beamforming chips. Also, discussions about the challenges that need to be addressed and the future development trends for this technology are given.
