– Python based design, simulation, fabrication of process-variability tolerant ultra-low loss SOI optical couplers for 1550/1300nm Photonic Reservoir chip, achieving transmission efficiency improvement from 74% to 99%. – Improved complex-valued python numerical model for Photonic Reservoir for BPSK, PAM, QAM modulations.

– Learned to strategize an evolutionary, modular product-platform approach for displays. – Setup of three measurement systems for colorimetric characterization of display panels 5” to 90”. – Suggested points to improve display mounting frame designs for ease of loading, mobility and integrating with the characterization setups in single mount, helped to reduce development, characterization cost & time. – Collaborated with people from departments of R&D, manufacturing, finance for guidance and feedback.

 Terahertz pulse generation in DSTMS crystals – Process engineering for synthesis of DSTMS through planned process flow, design-of-experiment, NMR characterization & analysis, optimization, purification in a chemistry lab environment.  Diffraction accounted mathematical modelling of Gaussian beam spots – Mathematica based modelling, analysis which provided 7% better intensity profile over traditional Gaussian.
