Silicon photonics

The first ever optical coherence tomography (OCT) images of cubic meter volumes have been produced, through an industry-academic collaboration. The advance could open up many new uses for OCT in industry, manufacturing and medicine. It also marks a milestone toward developing a high-speed, low-cost optical coherence tomography system on a single integrated circuit chip. James [...]

Microscopic Infrared Antenna on a Chip

A micron-scale spatial light modulator has been produced by research at Rice University. The spatial light modulator (SLM) is similar to ones used in sensing and imaging devices, but has the possibility of running orders of magnitude faster. Unlike other devices in two-dimensional semiconducting chips, these chips work in three-dimensional “free space.” The device, which [...]
