NIST researchers have developed advanced integrated photonics technologies using micro-and nano-fabrication techniques. The project focuses on creating compact, high-performance photonic devices using various materials including silicon, silicon dioxide, tantalum pentoxide, and AlGaAs. Key achievements include:
1. Efficient second harmonic generation in nanophotonic GaAs-on-insulator waveguides
2. Multifunctional integrated photonics in the mid-infrared using suspended AlGaAs on silicon
3. Infrared frequency comb generation and spectroscopy with suspended silicon nanophotonic waveguides
4. Full wafer bonding of III-V semiconductors to dielectrics for active integrated photonics
These developments demonstrate the potential of integrated photonics for various applications, including narrow linewidth semiconductor lasers, optical parametric oscillators, and frequency comb detection. The research showcases the capabilities of engineered photonic structures for compact, high-performance devices with reduced size, weight, and power requirements.
