Fiber Optical Solution and Exalos Publish Groundbreaking Paper on Next-Generation Inertial Measurement Units

We are excited to announce the publication of our collaborative research paper with Exalos. This joint effort marks a significant milestone in the development of cutting-edge inertial measurement units (IMUs) and highlights the innovative advancements achieved by the partnership between Fiber Optical Solution and Exalos.

The paper, titled “High-Precision Inertial Measurement Unit with Closed-Loop Fiber Optic Gyros – operated by a new 1550nm 3-fiber SLED transceiver”  details a revolutionary approach to IMU design.

Key achievements include:

  • Integration of a 1550nm Superluminescent Diode (SLED) transceiver module in a Butterfly (BTF) configuration.
  • Elimination of traditional optical components such as depolarizers, fiber couplers, and fiber-pigtailed photodiodes, which simplifies the manufacturing process.
  • Reduction in system costs and improved performance by minimizing number of components and number of splices in polarization-maintaining (PM) fibers.
  • Simplification of certification of IMU for military and space applications by reduction in the number of FOG components

The new IMUs are based on 3-axis closed-loop fiber optic gyroscopes (FOGs), leveraging a highly integrated optical transceiver that includes a 1:3 beam divider, a 3-channel optical circulator, and integrated receiver photodiodes.

This breakthrough not only enhances the performance and reliability of IMUs but also demonstrates the potential of collaborative innovation in fiber optic technologies.

The full paper is available at IEEE Xplore.

We are proud to contribute to advancements in the field of inertial measurement systems and look forward to exploring further collaborations with Exalos and other industry leaders.

Fiber Optical Solution and Exalos Showcase Breakthrough in High-Precision Inertial Measurement Technology

Fiber Optical Solution and Exalos Showcase Breakthrough in High-Precision Inertial Measurement Technology

In a joint presentation by EXALOS and FIBER OPTICAL SOLUTIONS (FOS) at the 61th DGON ISA symposium, experts from both companies demonstrated a novel integrated 1550 nm 3-fiber SLED transceiver module and its application in a high-precision Inertial Measurement Unit (IMU) for navigation.
The symposium took place in Brunswick (Braunschweig), Germany at October 22-23, 2024, as a face-to-face event.

The advanced 14-pin Butterfly (BTF) module is realized with a micro-optical, free-space bench technology.

EXALOS developer Stefan Gloor presented the new integrated SLED Transceiver Optical Module.

The broadband SLED emits an optical spectrum with 3dB bandwidth of 33 nm around a center wavelength of 1549 nm. The output is collimated into three output beams that are propagating through an optical circulator before being focused into an array of three PM output fibers. Efficient beam collimation and low-loss beam propagation on the optical bench in combination with high-efficiency coupling to the PM output fibers results in output power values of around 1.0 mW per fiber channel at low drive currents of only 150 mA.

Higher output power values are obtained at higher SLED drive currents. The polarization extinction ratio (PER) of each fiber port provides more than 15 dB.

Three integrated receiver photodiodes detect the returned light from the PM fiber loop of the corresponding FOG. The design provides low transmission loss as well as high isolation and, therefore, high wavelength and power stability against backward-propagating light.

All in all, the low-loss optical architecture in forward and backward direction offers power-efficient operation with low SLED drive currents and thus low TEC currents over the full temperature range from -40°C to +85°C.

Yuri Korkishko, CEO Fiber Optical Solutions, presented a series of new single-axis fiber optic gyroscopes (FOGs) and inertial measurement units (IMUs) for navigation systems. The new units were built on the basis of the novel integrated EXALOS SLED transceiver module.

The original, popular IMU required a wide range of discrete optical components, including depolarizers, fiber splitters or fiber-pigtailed photodiodes, as well as eleven splices of polarization-maintaining (PM) fibers.

Configuration of the existing model IFOS-5.

The new innovative IMU design is based on the new integrated EXALOS SLED transceiver module. The 14-pin Butterfly (BTF) module delivers broadband light with similar optical power levels and with a high polarization extinction ratio (PER) at three PM output fibers.
This allows the direct splicing to the three phase modulators (MIOC), reducing the number of PM fiber splices to only three:

 

Configuration of the new IFOS-5.

Thanks to the micro-optical integration of the three closed-loop FOGs in the 14-pin BTF module the number of external components and finally the IMU footprint is significantly reduced.The joint presentation, which was received with great interest, took place on Wednesday, 23-Oct-24.

Both companies looking forward to further successful cooperation in the development of innovative, market-leading products.

News of the project “Establishment of experimental integrated optical modulator production plant”

 

The project “Establishment of experimental integrated optical modulator production plant” started April 11, 2017.

During the project company already purchased and installed various equipment available on the market, while the new experimental equipment according to contract signed on 12.02.2019. is manufactured and delivered by company from Taiwan GAIA Technology Plus Co., LTD.

In April 2019, the Central Finance and Contracting Agency carried out a project inspection, verifying in person the project documentation and the equipment delivered to the project in accordance to the implementation requirements. At the end of 2019, the implementation of the project was extended to June 2020, due to the technological challenges in the production of experimental equipment and thus longer delivery time than initially planned was necessary.

Results of project foresee that in 2020 the new experimental technology with all experimental equipment and components will be implemented in real production environment.  After successful testing of the new technology, the company plans to launch a multi-function integrated optical module production in Riga, using a new reverse proton exchange technology in order to improve company’s final products – optical fiber gyro – its operational accuracy and durability.

The project is co-financed by the European Regional Development Fund, Operational Program “Growth and Employment” specific support objective 1.2.1. “Increase private sector investment in R & D” measure 1.2.1.4. “Support for the introduction of new products into production”.

Tā kā eksperimentālo iekārtu izgatavošanas laikā radušies tehnoloģiski izaicinājumi un iekārtu piegādei nepieciešams ilgāks laiks, nekā tika sākotnēji plānots, 2019. gada nogalē projekta īstenošana pagarināta līdz 2020. gada jūnijam ieskaitot.

Projekta rezultātā 2020. gadā reālā ražošanas vidē tiks ieviesta jauna, eksperimentāla tehnoloģija ar eksperimentālām komponentēm jeb iekārtām.
