The Stanford Photonics Research Center

The Digonnet group performs research on fiber optics. Previous areas of activity have included WDM fiber couplers, single crystal fibers, and integrated optics for fiber sensors. Current research interests include photonic-bandgap fibers, fiber sensors and sensor arrays, high-power ceramic lasers, fiber lasers and amplifiers, fiber gratings, slow light, and optical microcavities.

Professor Harris’s group does research on the growth, characterization, nanofabrication and device implementation of unique compound semiconductor materials. Harris’s group has pioneered the development of low bandgap GaInNAsSb materials for efficient long wavelength telecom lasers on GaAs substrates. His group also uses carefully controlled molecular beam epitaxy combined with nanolithography to prepare artificially structured materials with atomic layer control and enhanced performance. Recent achievements include new materials that extend the wavelength range that can be covered by VCSELs on GaAs substrates and, in collaboration with Miller’s group, new quantum well materials for high performance electro-absorption modulators that are compatible with Si substrates.

Professor Salleo’s group performs research on novel materials and processing techniques for large-area and flexible electronic/photonic devices. Materials systems of interest include thin films of polymeric semiconductors, nano-structured materials, and amorphous materials with particular emphasis on defects and structure/property studies. His group is developing ultra-fast laser processing techniques for patterning of materials used in electronics and photonics.
