Researcher: Ashish Kumar
Researcher CV: The education of Ashish Kumar includes a Master’s in Optical Engineering from Nanjing University of Science and Technology (NJUST) in China and a bachelor’s degree in electrical and electronics engineering from Vel Tech Dr. Rangarajan Dr. Sagunthala R&D Institute of Science and Technology, India. He works in the areas of Terahertz system design, simulation, analysis, and Polarization parametric indirect microscopy (PIMI). He has already published four papers in the field of terahertz and polarization parametric indirect microscopy (PIMI).
Objectives: This key objective of this research project is to study and develop photonic integrated mode locked lasers as optical signal sources for frequency-stable and low-phase noise Terahertz signal generation for pumping SBD mixers.
Expected Results: The vision of this research work is to develop a high repetition rate mode locked laser diode (MLLD) prototype using intra-cavity and extra-cavity structures that will provide a sub-harmonic continuous wave optical local oscillator signal required to generate high quality frequency stable and low phase noise THz signals. This research work will contribute to answering TERAOPTICS’ research Challenge I, III and V.
Planned secondment(s):
- to UDE (Prof. Andreas Stöhr), M14 for 1 months for round-robin tests of optically-mediated THz signal generation
- to ULIL (Prof. Guillaume Ducournau), M20 for 1.5 months, to find assembly solutions for THz sources based on mode locked laser
- to ACST (Dr. Oleg Cojocari), M28 for 1.5 months, to explore assembly of MLLD, high speed PDs for photonic LO signal for SBD receiver
