Spartex, just like Polymers research, new materials generally have a long Devlopment path to maturity, given that Polaris is working with a material that didn't exist until 2020 they are still in early-stage Development, perhaps in 5-10 years they can achieve commercial scale viability, here from Gemini

Given that ferroelectric nematic liquid crystals (FNLCs) were only definitively discovered and demonstrated in 2020, research into their reliability and stability for commercial applications is still in its early stages but is progressing rapidly. The focus of the work so far has been on proving the fundamental viability of the technology and demonstrating its key advantages, with reliability and stability being the next major areas of research.

Here's a breakdown of the work that has been done and the challenges that remain:

Work Completed and Positive Indicators:
Material Stability: Researchers have successfully synthesized and characterized FNLC materials that exhibit good phase stability at or near room temperature. This is a critical first step, as a material that only works in a very narrow temperature range would not be commercially viable.

Proof of Concept: The high-speed performance of FNLC modulators has been successfully demonstrated in laboratory settings. For example, a recent study demonstrated a hybrid silicon-FNLC modulator achieving 102 Gbit/s PAM-4 modulation. This proves the technology works for its intended purpose.

Scalability and Repeatability: One of the key advantages cited for FNLCs over competing technologies like electro-optic (EO) polymers is their inherent scalability. FNLCs spontaneously form a polar structure, eliminating the need for a "poling" step, which is a significant challenge for EO polymers and can be difficult to control. This suggests that FNLC-based devices may be more repeatable in a manufacturing environment.

Initial Reliability Studies: While not a long-term commercial-grade study, researchers have conducted tests to ensure the modulators can be operated with a stable domain alignment using a modest DC field. This indicates that the active state of the FNLC material is thermodynamically stable, a positive sign for long-term use.

Remaining Challenges and Areas of Focus:
Long-Term Performance Data: As the technology is so new, there is little to no public data on the long-term performance of FNLC modulators. Commercial readiness requires devices to operate reliably for many years (e.g., a decade or more) in demanding environments like data centers. This is a key area that is likely under active investigation by companies like Polaris Electro-Optics.

Thermal and Environmental Stability: The long-term stability of the FNLC materials under various conditions (e.g., high heat, humidity, and constant operation) is a critical factor. While research has shown good stability near room temperature, the performance in more extreme operational environments needs to be thoroughly proven.

Manufacturing and Integration: Moving from a lab-built prototype to a mass-produced, commercially viable product introduces many new variables. The processes for fabricating, packaging, and integrating these devices on a large scale need to be refined and proven to be reliable and consistent.

In summary, while the fundamental material science and initial performance demonstrations of FNLC modulators are highly promising, the technology is still in the phase of transitioning from the lab to commercial production. The focus has now shifted to rigorously testing and proving the reliability and stability of these devices under real-world conditions, a process that is essential for gaining the confidence of major customers in the telecommunications and data center industries.
