State-of-the-art nanophotonic devices based on semiconductor technology use total internal reflection or the photonic bandgap effect to reduce the waveguide core dimensions down to hundreds of nanometers, ensuring strong optical confinement within the scal ...
We present recent implementations of microwave photonic filters using the following two technologies: InP-based MDR (microdisk resonator) on and coupled to a nanophotonic SOI waveguide and dynamic Brillouin gratings (DBGs) in polarization maintaining fiber ...
We experimentally demonstrate that a novel type of photonic delay line based on movable dynamic grating reflectors generated in polarization maintaining fibers can provide continuously tunable signal delaying for high capacity optical data streams and wide ...
The series of precisely spaced, sharp spectral lines that form an optical frequency comb is enabling unprecedented measurement capabilities and new applications in a wide range of topics that include precision spectroscopy, atomic clocks, ultracold gases, ...
By imaging the angular spectrum of optical modes confined within subwavelength volumes, we investigate the impact of metallic and dielectric surrounding layers on the optical emission properties of planar silicon photonic crystal cavity. By scanning a mirr ...

An alternative route to plasmon-controlled fluorescence for improving the detection of fluorescence is proposed. In place of a metallic layer, a suitable silicon-based one-dimensional photonic crystal is used to generate a Bloch surface waves-coupled emiss ...
Photonic crystals (PhC) are periodically structured electromagnetic media, in which light within some frequency ranges cannot propagate through the structure. Such frequency ranges are commonly referred as photonic band gaps (PBG). The length scale of the ...
In this paper, a semi-classical formulation for modeling photonic-crystal (PC) structures with a four-layer multi quantum well (MQW) active region is presented. The formulation treats the electromagnetic fields as a classical entity, while employing the qu ...
We demonstrate the effect of rapid thermal annealing on heavily Si-doped AlN/GaN quantum wells. After 1000 degrees C annealing during 5, 10, and 20 min, the dominant effect was interdiffusion of Si rather than intermixing between the Al and Ga atoms. Both ...
The Gemperline research group is currently working on a research project to characterize chemical batch reactions in slurry mixtures with light scattering properties. One of our primary goals is to determine light absorption and light scattering properties ...
