Caltech’s new fiber-like photonic chips achieve record-low visible-light loss, enabling more coherent lasers and next-generation quantum and sensing technologies.

From sci‑fi vision to fiber‑optic engineering The core promise of a quantum internet is simple to state and hard to build: information encoded in quantum states would be impossible to copy without ...

Charles Kao, whose work in the 1960s laid the foundation for today’s long-distance fiber-optic networks, has won a share of this year’s Nobel Prize in Physics. Kao, sometimes referred to as the ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical fiber at visible wavelengths. This accomplishment paves the way for a new ...

When it comes to developing faster computers, Intel has seen the light. The chipmaker recently launched a new effort inside its Microprocessor Research Lab aimed at examining a move from using ...

Faculty study light-based systems, light-based components, and the underlying physical behavior of light. At a fundamental level, these faculty research basic physical processes of light, including ...

Optical fiber cabling will be the only network connectivity capable of supporting data rates of 50Gb/s and beyond in typical network applications. This can be demonstrated by referencing ...
