Simulation and optimization of BaTiO3-based edge couplers

Having demonstrated conclusive results in both light guiding and modulations, BaTiO3 (BTO) presents great potential in demonstrating a monolithic integration of PICs. This platform could indeed present scalable circuits that include both the passive and active devices for high speed modulation. However The transmission's efficiency is currently limited by the fibers to chip losses. Edge couplers (EC) appear as a suitable approach to address this issue while guaranteeing a simplified layer stack. Show details 

Electro-optical frequency comb: CMOS based Electrical oscillator design

Optical frequency combs have emmerged with the need for precise measurement of optical frequencies. Since their first practical realisation, they’ve enabled a plethora of applications going way past metrology, such as optical and wireless communcations, spectroscopy ranging and radar. Electro optical frequency combs integrated within a plasmonic-photonic platform is a key tool for high resolution THz radars and high speed communication. A low phase noise electrical oscillator represents a key element of such a platform Show details 

Fabrication and Characterization of Low-Loss SiN Waveguides

Silicon nitride (SiN) has become a key material in integrated photonics and is increasingly seen as a potential replacement for silicon as the main waveguiding platform. Its advantages—low optical losses, a wide transparency range, high power handling, and easier coupling to fiber modes—make it ideal for a broad range of applications. These include telecommunications, data centers, biosensing, LiDAR, and emerging quantum technologies. In our lab, we focus on its application in heterogeneous integration with an active material for electro-optic modulation, enabling high-speed and efficient signal processing. Show details
