Photonics researchers report breakthrough in miniaturizing light-based chips:
Photonic integrated circuits that use light instead of electricity for computing and signal processing promise greater speed, increased bandwidth, and greater energy efficiency than traditional circuits using electricity.
[...] Using a material widely adopted by photonics researchers, the [University of] Rochester team has created the smallest electro-optical modulator yet. The modulator is a key component of a photonics-based chip, controlling how light moves through its circuits.
In Nature Communications, the lab of Qiang Lin, professor of electrical and computer engineering, describes using a thin film of lithium niobate (LN) bonded on a silicon dioxide layer to create not only the smallest LN modulator yet, but also one that operates at high speed and is energy efficient.

The month of August is winding to a close. Here are a few updates on site activity. If you are interested, please read on after the fold. Otherwise, a new story will be along shortly.

You cannot compute with light alone. You must have an interlacing of dark with light - an ever-pulsing interplay of excitements.
