Sivers, LioniX, Chilas Partner on Narrow-Linewidth Tunable Lasers

Sivers Photonics, a subsidiary of Sivers Semiconductors, has partnered with LioniX International and Chilas BV to develop and supply a narrow-linewidth integrated O-band continuous-wave tunable 1310-nm laser. The laser, introduced by LioniX, addresses demand for O-band solutions from OEMs, advanced laboratories, and industrial sensor manufacturers working in communications (passive optical networks, fiber optic communications), lidar, and molecular analysis markets.

Per the partnership, Sivers will supply a customized optical amplifier developed on its InP100 product platform to power the laser. Chilas, as the end user, will provide product testing services for the assembled PIC, and it will offer the product as part of its laser portfolio.

According to LioniX, the laser showed a tuning range of 25 nm during testing, spanning 1298 to 1325 nm, and achieving a maximum power output of 2.5 dBm at 240 mA. The semiconductor amplifier from Sivers Photonics provides electrical pumping in an 800-μm long chip, LioniX said.

There are 442 suppliers of Lasers in the Photonics Marketplace.

Glossary

laser: A laser, which stands for "light amplification by stimulated emission of radiation," is a device that produces coherent and focused beams of light through the process of optical amplification based on the principles of quantum mechanics. Key features of lasers include: Stimulated emission: The operation of a laser is based on stimulated emission, a quantum phenomenon where atoms or molecules in an excited state release photons when they encounter other photons. This process leads to...
photonic integrated circuit: A photonic integrated circuit (PIC) is a compact and integrated device that incorporates multiple photonic components and functions on a single chip, similar to the way electronic integrated circuits (ICs) integrate various electronic components. The goal of a photonic integrated circuit is to manipulate and control light signals for applications in optical communication, sensing, signal processing, and other photonic technologies. Key points about photonic integrated circuits: Integration...
lidar: Lidar, short for light detection and ranging, is a remote sensing technology that uses laser light to measure distances and generate precise, three-dimensional information about the shape and characteristics of objects and surfaces. Lidar systems typically consist of a laser scanner, a GPS receiver, and an inertial measurement unit (IMU), all integrated into a single system. Here is how lidar works: Laser emission: A laser emits laser pulses, often in the form of rapid and repetitive laser...
amplifier: A device that enlarges and strengthens a signal's output without significantly distorting its original waveshape. There are amplifiers for acoustical, optical and electronic signals.
