Non-thermal (thermally insensitive) packaged Fiber Bragg Grating (FBG)

Fiber Bragg Gratings (FBG) are highly sensitive to temperature changes. Their thermal sensitivity is approximately 6.7 ppm/°K (at a wavelength of 1550 nm, it is +0.11 pm/°K). Non-thermal encapsulated FBGs are designed to passively compensate for the thermal sensitivity of FBGs through the expansion matching of the shell elements and the wavelength shift of the FBG under temperature influence. This design allows customers to achieve all the advantages of Fiber Bragg Gratings while maintaining high wavelength stability over a wide temperature range

1550nm Polarization Maintaining Fiber Polarization Beam Splitter

The Polarization Beam Splitter (PBS/PBC) is used to couple two orthogonal polarized light beams into a single optical fiber, or to couple the orthogonal polarized light from a single output into two separate optical fibers. It can also be used in reverse to couple two orthogonal polarized light beams from a polarization-maintaining fiber into a single-mode output fiber. These devices are commonly used for power combining in pump lasers, improving the power of fiber lasers. An important application of these devices is in polarization multiplexing and demultiplexing technology, which enhances the capacity of optical systems.
