Qubits are the building block for quantum technology, and finding or building qubits that are stable and easily manipulated is one of the central goals of quantum technology research. Scientists have ...

Lasers have revolutionized the world since the 60s and are now indispensable in modern applications, from cutting-edge surgery and precise manufacturing to data transmission across optical fibers. But ...

Scientists have successfully miniaturized a powerful erbium-based biber laser on a silicon-nitride photonic chip. Since typical erbium-based fiber lasers are large and difficult to scale down, the ...

As a complement to silicon-based photonic chips, lithium niobate thin film (LNOI) has become a research hotspot in the field of optoelectronic integration due to its outstanding nonlinear, ...

Erbium-doped fiber lasers represent a cornerstone of modern photonics by exploiting the 1.53–1.62 µm gain band of erbium ions incorporated into silica-based fibers. Their intrinsic compatibility with ...

Optical image of a hybrid integrated erbium-doped photonic integrated circuit-based laser, providing fiber-laser coherence and previously unachievable frequency tunability. Lasers have revolutionized ...
