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

Agarwal A.M., Cai Y., Kimerling L., Lin P-T, Patel N.S., Singh V., 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 [...]

Mid-infrared Silicon Platform for Chip-scale Chemical Sensors

Hensley J., Hu J., Kimerling L., Lin H.-Y.G., Lin P-T, Luzinov I., Murthy Agarwal A., Patel N.S., Richardson K., Singh V., Massachusetts Institute of Technology, US

Mid-Infrared optofluidics based silicon sensor platforms are demonstrated. Silicon is a great candidate for mid-infrared optofluidics for the following reasons: (1) Silicon has a broad transmission window up to 7 um (2) Silicon offers CMOS [...]

SUEX for High Aspect Ratio Micro-Nanofluidic Applications

Goettert J., Johnson D., Singh V., Yemane D., DJ DevCorp, US

Microfluidics applications can benefit from a dry film approach in multiple ways – particularly in the preparation of multi-layer, multi-level fluidic channels and structures on patternable substrates and covers. In addition, polymer microreactors and other [...]

Fabrication and Characterization of HAR Microfluidic Device to Concentrate Microalgae

Bargiel J., Goettert J., Lane C., Nguyen Q., Singh V., Stephenson F., Yemane D., Louisiana State University, US

Algae are a promising candidate for large-scale production of biofuels, an important source of renewable energy [1]. A significant portion (20-40%) of the cost in the traditional processing comes from concentrating (dewatering) the algae from [...]

Preparation and Characterization of BiFeO3 Nanosystems as Visible Light Driven Photo-degradation of Organic Compounds

Dunn S., Hengky C., Loh L., Singh V., Nanyang Polytechnic, SG

The use of renewable or low energy sources for the degradation of organic pollutants has generated broad interest in both scientific research and potential applications in recent years. Research on semiconductor photocatalysis came sharply into [...]
