Patricia Bath – A history to be learned, a legacy to be remembered

Every February and March, the world puts a spotlight on Black history and women’s history. This is because these stories have been left out of the history books and our collective consciousness for far too long. This is particularly true when looking at science. Making connections, building supportive networks, sharing experiences and best practices are a vital part of being a...

You asked IBM Research scientist Jessie Rosenberg “anything” about silicon photonics

Silicon photonics uses light, versus electricity, to send signals from a microchip. IBM engineers use these pulses of light to increase the connectivity and bandwidth between datacenters for faster data transfer over longer distances. But silicon photonics isn’t just for datacenters. IBM sees the technology helping improve everything from IoT sensors to quantum photonics.

OIDA Workshop on Integrated Photonics High Volume Packaging

Progress continues on the design and clean room fabrication of integrated photonics, and companies have commercialized products based on integrated photonics on both the InP and silicon platforms.  There is growing awareness that the chip fabrication is less of a barrier to commercialization, and attention is increasingly turning to the cost of the overall package. This cost includes the...

Perspective views from Industry & Government on Nanophotonics

Similar to the success of dense electronic component integration towards creating VLSI circuits, the photonic and optoelectronic industry is following similar integration schemes, terming the name “photonic integrated circuits” (PIC). However, all-Silicon PIC cannot currently complete all the functions. Alternatively, III-V platform, such as InP material system, still occupies a...

The Early Photon Gets the Worm

One of the biggest problems with using light to analyze biological tissue is that photons in the visible and near-visible spectrum have a very high probability of scattering multiple times as they propagate through the tissue. This is a well-known problem that restricts high-resolution optical microscopy to tissue thicknesses of only a few microns. It has also led researchers to develop...

Salt and Pepper (Noise): Key Ingredients for Imaging Blood Flow

We’ve all experienced that “salt-and-pepper”, or white noise when our favorite television show cuts out on us. Well it turns out that similar “speckle” patterns are also seen when projecting laser light onto biological tissue, owing to interference patterns of the monochromatic light source. Now you might say, “so what!” and that’s probably what...
