ER Doped Photonic Integrated Circuits: From on-Chip Amplifiers, Tunable Low-Noise Lasers to Mode-Locked FS Sources

2025

Abstract

Erbium amplifiers enable low-noise, crosstalk-free optical communication. Recent advances in on-chip Erbium-doped amplifiers using ion implantation have enabled Er based gain in low loss silicon nitride waveguides, with scalable manufacturing that is foundry compatible. I will discuss both amplifiers (with > 200 mW of output power), lasers (fully C-L band tunable), as well as mode locked lasers with 100 pJ pulse energy based on this technology.

Laser

A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light that is coherent.

Optical amplifier

An optical amplifier is a device that amplifies an optical signal directly, without the need to first convert it to an electrical signal. An optical amplifier may be thought of as a laser without an optical cavity, or one in which feedback from the cavity is suppressed. Optical amplifiers are important in optical communication and laser physics. They are used as optical repeaters in the long distance fiberoptic cables which carry much of the world's telecommunication links.

Fiber laser

A fiber laser (or fibre laser in Commonwealth English) is a laser in which the active gain medium is an optical fiber doped with rare-earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, thulium and holmium. They are related to doped fiber amplifiers, which provide light amplification without lasing. Fiber nonlinearities, such as stimulated Raman scattering or four-wave mixing can also provide gain and thus serve as gain media for a fiber laser.
