Ratish Rao Nagaraj Rao

"I received my PhD from Laboratoire Hubert Curien at l'Université de Saint-Étienne, where I focused on the fabrication of grating waveguide structures using laser interference lithography (LIL) for spectral stabilization and wavelength multiplexing of diode lasers and thin-disk lasers.

Through the WACQT-Finnish postdoctoral fellowship, I have joined the Nonlinear and Quantum Photonics (NQP) group at Albanova, KTH. My work focuses on developing scalable hybrid photonic devices for advanced quantum communication, with an emphasis on silicon–lithium niobate (Si–LiNbO₃) electro-optic modulators.

My research interests include photonic integrated circuits (PICs), micro- and nano-structuring, nanofabrication, and hybrid photonic platforms.
