Frequency-tuning of nano-photonic resonators for quantum networks with Erbium spins

Individual erbium spins in silicon and related materials show unique
promise for the realization of a global quantum network. To enable
single-spin control, the spins have to be integrated into optical
resonators of small size and high quality. Our group at the
Max-Planck-Institute of Quantum Optics ( ) uses silicon nanophotonic structures to achieve this goal. While
individual resonators can be tuned by gas condensation, it is an
outstanding challenge to tune arrays of them into resonance both with
one another and with the Erbium spins. To achieve this goal, we will
analyze and implement several approaches based on nano-mechanics and

Physics: Nanophotonic structures, spins in semiconductors
Techniques: Nanofabrication, Nano-optics, laser-spectroscopy at
cryogenic temperatures.
