Photonic characterization analyzes the optical performance of the photonic device or photonic link for a system. Here, my research involves charaterisation of various novel photonic sources like laser and optical frequency combs in terms of RIN, linewidth, bandwidth etc. I also investigate the RF measurements like S parameters, lineraity , P1dB, SFDR, Noise figure, Phase noise etc. for a photonic based RF link. Characterisation of the external optical modulators based on the specific required parameters is also a part of my invetsigation.
