We show the real-space observation of fast and slow pulses propagating inside a photonic
crystal waveguide by time-resolved near-field scanning optical microscopy. Local phase and …

The negatively charged nitrogen-vacancy (NV−) center in diamond has realized new
frontiers in quantum technology. Here, the optical and spin resonances of the NV− center are …

Electrically driven single-photon emitting devices have immediate applications in quantum
cryptography, quantum computation and single-photon metrology. Mature device fabrication …

Room temperature single-photon emission and quantum characterization is reported for
isolated defects in zinc oxide. The defects are observed in thin films of both in-house …

Heterogeneous integration of III-V compound semiconductors on Silicon on Insulator is one
the key technology for next-generation on-chip optical interconnects. In this context, the use …

We show reduction in the emission from nitrogen‐vacancy (NV) centers in single crystal
diamond due to exposure to hydrogen plasmas ranging from 700 C to 1000 C. Significant …

The eigenfield distribution and the band structure of a photonic crystal waveguide have
been measured with a phase-sensitive near-field scanning optical microscope. Bloch modes, …

The negatively-charged nitrogen vacancy (NV − ) center in diamond is of great interest for
quantum information processing and quantum key distribution applications due to its highly …

We demonstrate the integration of bright, fully polarized single-photon emitters readily
created by thermal oxidation of cubic silicon carbide (SiC) into microdisk resonators. The …

A highly efficient Y-junction based on a planar photonic crystal (PhC) platform is presented.
The PhC consists of a triangular array of holes etched into a GaAs/AlGaAs heterostructure, …
