Optimum capture of the incident light through efficient photon management is considered a crucial requirement for realization of ultra-efficient photovoltaic devices. For this purpose, diffraction gratings have been applied for photon management in solar energy conversion. Specifically, due to the hexagonal arrangement of the grating structure, hexagonal gratings can be favorable in integrated...
Fiber lasers have many applications in industry and medicine because of their unique characteristics—an all-fiber design, compact size, cost-effective production and operation, and no need for re-alignment and external cooling. A fiber laser emitting in the infrared region has applications in optical communication, sensing, spectroscopy and nonlinear optics.
The Photonics Research Group is...
In recent decades, thin-film technologies have emerged as front-runners in solar light harvesting for their highly-reduced material volume and cost. Absorption lengths exceeding film thickness restricts absorption, but this scale allows us to take advantage of state-of-the-art light-trapping and field enhancing techniques that increase photon lifetimes. One type of structure is the scattering...
Optical tweezing is a well-known phenomenon for trapping or manipulating dielectric and metallic nanoparticles. The application of metallic nanoparticles in sensing has attracted a lot of attention due to their unique optical and chemical properties. We have developed a unique plasmonic structure on the surface of a multimode tapered optical fiber by optical tweezing of gold nanorods. In order...
