Novel T centers in silicon hold great promise for quantum networking applications due to their telecom band optical transitions and the long-lived ground state electronic spins. An open challenge for advancing the T center platform is to enhance its weak and slow zero phonon line (ZPL) emission. In this work, by integrating single T centers with a low-loss, small mode-volume silicon photonic crystal cavity, we demonstrate an enhancement of the fluorescence decay rate by a factor of F = 6.

- A nanoplasmonic interferometric biosensor is introduced, utilizing the selective excitation of plasmonic modes via a nanoslit for enhanced biosensing sensitivity.
- The system leverages the interference of counter-propagating surface plasmon polaritons to excite specific dipolar and quadrupolar modes based on analyte-induced phase shifts, leading to significant changes in light transmission patterns.
- The sensor demonstrates impressive bulk and surface sensitivities, with the ability to fine-tune performance characteristics by adjusting the nanoslit's width, making it adaptable for various sensing applications.
