Muhsin Ali’s research focus is on low-profile and efficient monolithically grown photonic emitters for mmWave applications. He did B.S. Telecommunication Engineering from FAST, Pakistan and M.S. Electrical Engineering from NUST, Pakistan where he also worked as research assistant. His research interests lie in the areas of wireless communication, particularly antenna designing, to biomedical engineering. Apart from academics, he has professional experience of over a year as an RF Drive Test Engineer and RF Analyser (GSM/WCDMA/LTE) in Delta Turkish Telecom, Saudi Arabia.

His project’s focus in FiWiN5G will be enhancing the radiated power in the millimetre wave range from high speed photodiodes using monolithic antennas. In recent years there has been increasing interest in photonic emitters (Fig. 1) in millimetre wave (mm-wave) frequency range the purpose of which is to convert and radiate the mm-wave optical signals. The use of wide bandwidth and high output power optical-to-electrical converters (e.g. photodiodes) has made this process realistic by replacing the conventional, expensive and bulky, electronic RF signal generators.

The scope of this project is to enhance the radiated power of mm-wave photonic emitter in order to support the user-level high data rate transmission of more than 1Gbps, as specified for next generation 5G networks. Since the 5G devices are expected to be highly mobile and handy, it could be achieved by minimising the size of RF front-end. The idea is to design and optimise the planar antennas on low-cost laminates and to integrate them with high speed photodiodes either in hybrid or monolithic fashion. The potential of both the integration methods is also to be investigated. The end result is expected to be an efficient and low-profile on-chip antenna to radiate the modulated mm-wave carrier wave into free space.
