About me
I am a Doctoral Researcher in the Nanophotonics group at Tampere University, specializing in the end-to-end development of photonic integrated circuits (PICs). My work spans numerical modeling and device optimization, cleanroom microfabrication, and precision optical testing. By bridging design theory with hands-on prototyping, I focus on creating high-performance components engineered for next-generation optical communications, sensing platforms, and integrated photonic technologies
Fields of expertise
My technical expertise encompasses the design, simulation, fabrication, and characterization of integrated photonic devices and semiconductor nanostructures. I have hands-on experience with cleanroom microfabrication processes, photonic device modeling, and optical testing. A summary of my key technical skills is provided below.
Cleanroom microfabrication: Photolithography, electron beam lithography (EBL), reactive ion etching (RIE), PECVD, ebeam metal evaporation, wet chemical etching, wafer dicing, and scanning electron microscopy (SEM), Ellipsometry, Profilometry and Filmetrics for thin-film measurement.
Photonic device simulation: Ansys Lumerical (FDTD, MODE, INTERCONNECT, FEEM), GDSFactory, KLayout, and Python for the design, optimization, and analysis of waveguides, micro ring resonators, directional couplers, phase modulators and photonic integrated components.
Optical characterization: Free-space and fiber-coupled setup alignment, edge/vertical grating coupling, optical spectrum analyzer (OSA), tunable laser source (TLS) testing, transmission and insertion loss measurements, polarization-resolved measurements, power meters, photodetectors, near-field/far-field beam profiling, and performance analysis of active/passive photonic components.
