In the 1960s, physicists showed how light could interact with itself in intriguing ways thanks to a process known as second-harmonic generation. In the right kind of material, two photons of a certain ...

Programmable optics startup Lumotive has added a few more strategic backers to its recent Series B round. Redmond, Washington-based Lumotive reopened its recent Series B funding round to bring in ...

Cornell researchers have built a programmable optical chip that can change the color of light by merging photons, without requiring a new chip for new colors. This form of nonlinear photonics could ...

Researchers at the University of Twente, The Netherlands, have developed a programmable integrated microwave photonic filter with what they describe as “a record-breaking dynamic range”. This ...
