Mid-infrared Silicon Microphotonic Cavities with High Resonance of Q~10^5

Lin P-T, Singh V., Cai Y., Patel N.S., Kimerling L., Agarwal A.M., Massachusetts Institute of Technology, US

One dimensional photonic crystal 1D-PhC silicon waveguide resonators with quality factor, Q~10^5, are demonstrated at mid-infrared wavelengths between 2 um to 5 um. Silicon has several advantages for mid-infrared applications including its broad mid-infrared transmission [...]

The Large Scale Fabrication of Protein Nanoarrays Based on Nanosphere Lithography

Cai Y., Ocko B.M., Brookhaven National Laboratory, US

Many emerging biological and medical applications involve the development of protein arrays at nanoscale.1 Dip-pen lithography2 nanografting and conducting tip AFM writing are capable of creating nano-protein patterns with 50-100 nm resolution over small surface [...]
