Integrated Photonics

Currently looking to complete a project in integrated photonics. See below a summary of the project:

Polarization manipulation is one of the essential functions that enable polarization insensitive integrated photonic circuits. Although many efforts were dedicated to create adiabatic polarization manipulation devices on the silicon-on-insulator platform, a few were realized on the well-established lithium niobate material. The aim of this thesis is investigate the use of coupled mode theory to create efficient adiabatic polarization manipulation devices with minimal footprint. This work focuses in particular on the realization of adiabatic polarization beam splitters/rotators on the lithium niobate on insulator (LNOI) platform rib-loaded by silicon nitride (SiN) for telecommunications. Major contributions made by this project include the development of a design approach based on coupled mode theory that enables the creation of adiabatic devices with minimal footprint. This approach is verified by creating polarization mode converters on the silicon-on-insulator (SOI) platform. Next, several studies on the deposition, patterning and bonding of SiN thin layers are presented. Finally, an adiabatic polarization beam splitter/rotator (PBSR) is realized on the SiN/LNOI platform. The PBSR consists of two stages: an adiabatic mode converter and an adiabatic coupler. This pushes the boundaries towards high speed and low power communication as well as applications for different wavelengths regimes.
