Tip-Tilt-Piston Micromirror with Integrated Large Range Variable Focus for Smart Lighting Systems

Morrison J., Imboden M., Little T.D.C., Bishop D.J., Boston University, US

Modern fabrication techniques are enabling the adoption of micro-opto-electromechanical systems devices in applications never anticipated. Low-cost lighting systems can exploit micromirrors to both enable directed or sculpted light and to support short-range optical communications. The [...]

Light Trapping in Solar Cells Using Nanostructured Reflectors: A Responsivity-Based Model Applied to Waveguide Mode Matching

Shahriad T., Shepard S.R., Louisiana Tech University, US

Although theoretically predicted that periodic photonic nanostructures can outperform the pseudo random structures in light trapping in solar cells, still the disputation regarding this topic is at the top. To enlighten the world about the [...]

Numerical Modeling of Nanoscale Silicon Photodetectors that Use Electromagnetic Resonance Modes to Enhance Performance

Crouse D., Keshavareddy P., The City College of New York, US

Several high responsivity, high bandwidth, low bit error ratio (BER) nanoscale Si photodetectors are modeled including metal-semiconductor-metal photodetectors (MSM-PD), MSM-PDs fabricated on silicon-on-insulator substrates, and avalanche photodiodes. The authors have analyzed surface plasmons and other [...]
