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

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 ...

With the rise of quantum computers, the security of our existing communication systems is at risk. Quantum computers will be able to break many of the encryption methods used in current communication ...

Optical fibers have become the foundation of modern data transmission, used for everything from telecoms and internet services to governmental and space applications. This is because they’re capable ...

Engineering physics major Katie Wootten was named a Stephen Halley White Undergraduate Research Award recipient this semester, in recognition of her outstanding research project. The award is the ...

The thought experiment began with a number. Single-mode fiber optics can now transmit data at 256 terabits per second over 200 kilometers. Based on that capacity, ...

An explosion of data, driven by more sensors everywhere and the inclusion of AI/ML in just about everything, is ratcheting up the pressure on data centers to leverage optical interconnects to speed up ...
