The global All-Fiber Lyot Depolarizer market size is predicted to grow from US$ 169 million in 2025 to US$ 406 million in 2031; it is expected to grow at a CAGR of 15.7% from 2025 to 2031.

The all-fiber Lyot depolarizer is a passive device that uses the coherence characteristics of the polarization state to generate a pseudo-random polarization output with a low degree of polarization (DOP) for any polarization input state (SOP). It is based on the principle of the Lyot depolarizer and is formed by fusing two sections of polarization-maintaining optical fibers with a specific length ratio and relatively rotated refractive index axes. It uses the time delay characteristics of light transmitted along the two birefringence axes of the polarization-maintaining optical fiber to separate the two polarization eigenstates of polarized light in time, thereby achieving depolarization of the input light.

With the continuous development of optical technology, the performance of all-fiber Lyot depolarizers continues to improve, and the application areas continue to expand, which will drive the growth of the market size. In the fields of military, aerospace, fiber-optic communications, etc., the demand for high-performance and high-stability all-fiber Lyot depolarizers continues to increase, which will promote the expansion of the market size. At present, there are many companies in the world producing all-fiber Lyot depolarizers, and the market competition is fierce. However, with the continuous advancement of technology and the continuous expansion of the market, some companies with core technologies and market advantages will gradually stand out and occupy a larger market share.
