Silicon Vacancy (SiV) color centers in diamond have emerged as suitable candidates for Qubits. In this work, waveguides coupled to single SiV centers which are Ion-Implanted will be used for single photon manipulation experiments. Further engineering of the waveguide structure enables on-chip Hong-Ou-Mandel single photon interference experiments.

Femtosecond laser writing has emerged as a powerful tool for integrated photonic and microfluidic in transparent materials. In this work, we will used laser micromachining to realize integrated circuits in diamond consisting of Bragg reflectors, directional couplers and microfluidics for lab-on-a-chip applications.

It has been shown that single femtosecond laser pulse has the ability to create defects which behave as single photon sources. This technique will be researched on other materials like hBN, GaN, SiC and SiN. Laser writing will be employed to form single photon sources with good spectral properties in these upcoming materials for future quantum technologies.
