Description
The Ytterbium‑Doped Fiber Amplifier (YDFA) for 1.0 µm from DK Photonics is a high‑performance optical amplifier designed for applications in the 1030–1100 nm wavelength band. Based on ytterbium‑doped gain fiber and a highly stable semiconductor pump architecture, this amplifier delivers high saturated output power levels (up to 33 dBm class), wide gain bandwidth, and low noise figure. It is available with either HI1060 single‑mode fiber or PM980 polarization‑maintaining panda fiber, making it suitable for both conventional fiber‑optic systems and polarization‑sensitive setups such as precision sensors and coherent laser sources.
Engineered for flexibility and ease of integration, the YDFA platform is offered in two configurations: a user‑friendly desktop unit and an ultra‑compact module. The desktop version is ideal for laboratory and R&D environments, providing front‑panel controls for pump current and output power adjustment, as well as clear status indications. The modular version is optimized for embedded use in OEM systems, where small footprint, low power consumption, and remote control are critical. Both formats support host‑computer control and serial command operation, ensuring seamless integration into automated test setups and industrial systems.
In typical operation, the amplifier accepts input powers from 0 to +10 dBm and provides a range of saturated output power options (17, 20, 23, 25, 26, 27, 30, and 33 dBm). A low typical noise figure around 5 dB and gain flatness of approximately 3 dB across the 1030–1100 nm band help preserve signal integrity, while high input/output isolation (greater than 30 dB) improves system stability and minimizes back‑reflection sensitivity. Polarization‑related parameters are carefully controlled: polarization dependent gain is typically below 0.3 dB and polarization mode dispersion is on the order of 0.5 ps, supporting demanding applications where polarization and phase must be maintained.
The amplifier incorporates both Automatic Current Control (ACC) and Automatic Power Control (APC) modes, allowing users to select between pump‑stabilized and output‑power‑stabilized operation depending on system requirements. This dual‑mode control strategy is common in advanced fiber amplifiers worldwide and enables stable long‑term performance, even under varying environmental conditions or input‑power fluctuations. In laboratory use, researchers can benefit from straightforward front‑panel operation, while system designers can leverage digital control via RS‑232 (DB9 interface on the module) to fine‑tune gain, monitor status, and implement feedback loops.
From an integration standpoint, the YDFA is designed to align with typical mechanical and electrical requirements found across similar products in the global market. The desktop version operates from a universal 100–240 V AC power supply with power consumption under 30 W and is housed in a rugged enclosure measuring approximately 260 mm (W) × 280 mm (D) × 120 mm (H). The compact module version is powered from a low‑voltage 5 V DC supply with power consumption below 15 W and comes in a 125 mm (W) × 150 mm (D) × 20 mm (H) package that can be mounted into higher‑level assemblies or 19‑inch rack systems. Both options are specified for operation in the −5 °C to +55 °C temperature range and 0–70% relative humidity, enabling deployment in typical laboratory, industrial, and field environments.
Thanks to its combination of high output power, broad wavelength coverage, and low noise, this ytterbium‑doped fiber amplifier is well suited for a wide variety of 1.0 µm‑band applications. In fiber communications and free‑space optical links, it can boost signals in specialty 1 µm systems, testbeds, and experimental transmission lines. In fiber laser setups, the YDFA can act as a power amplifier or pre‑amplifier stage for narrow‑linewidth seed lasers around 1030–1080 nm, supporting both continuous‑wave and modulated operation. In fiber‑optic sensor systems, such as distributed or point sensors operating in the 1.0 µm window, the amplifier provides the high gain and stability required for enhancing signal‑to‑noise ratio and extending sensing range, while maintaining the polarization characteristics needed for interferometric or polarization‑based measurement techniques.
The use of HI1060 single‑mode fiber output is well aligned with many commercial 1.0 µm sources and components, providing low‑loss splicing and compatibility with standard components found in the market. For applications requiring strict polarization control, the PM980 panda fiber output helps maintain a defined polarization state over the full amplifier chain, matching industry practices for coherent detection, high‑precision metrology, and advanced laser processing.
