Addressing a long-standing challenge in photonic integrated circuit design, researchers demonstrate that a miniature erbium-doped waveguide amplifier provides efficient and high-power optical ...

A new amplifier developed in Sweden enables the transmission of ten times more data per second than those of current fiber-optic systems. Developed by a research team from Chalmers University of ...

Optical amplifiers based on chirped pulse amplification (CPA) are used to generate high intensity pulses. In the CPA scheme, a weak temporally stretched seed pulse is amplified to high energy in a ...

A focus-stacked macro photograph of a fabricated gallium phosphide photonic chip featuring multiple spiral waveguides and other test structures. The chip width is just 0.55 cm across. Due to the high ...
