Abstract

Nowadays, optical coherence tomography (OCT) technology is well known in the in-vivo disease diagnose, attributed to the low-cost operation of the three-dimensional medical imaging. In this thesis, we investigate the potential of using photonic integrated circuits (PIC) technologies for replacing the free space optical components in the OCT. The use of Silicon-photonics CMOS based technologies are employed in investigating the building blocks of the PIC used for enabling replacement of free-space optics interferometer part in OCT system. The building block of the structures include the roughness consideration, tapered waveguides structures, bend loss analysis, coupler analysis, and cross talk in intersecting waveguides. The technologies platform was developed based on Silicon-on-Insulator (SOI) technologies. Future directions of the concept are also presented in this thesis.
