Non thermal (heat insensitive) encapsulated Bragg fiber grating FBG

Bragg fiber Bragg grating is highly sensitive to temperature changes. Their thermal sensitivity is approximately 6.7 ppm/⁰ K (+0.11 pm/⁰ K at a wavelength of 1550 nm). Non thermal encapsulated FBG aims to passively compensate for the thermal sensitivity of FBG through the expansion fit of shell components and wavelength shift of FBG under temperature influence. It enables customers to achieve all the advantages of fiber Bragg gratings while maintaining high wavelength stability over a wide temperature range.

1550nm heat insensitive encapsulated fiber Bragg grating

Fiber Bragg Grating is widely used in the field of communication as a wavelength filter. The center wavelength of fiber Bragg grating is highly sensitive to external temperature changes. This package uses a unique TE technology to ensure that the center wavelength of the grating is not affected by temperature.

Fiber Bragg Grating for Fiber Laser Applications

Fiber Bragg Grating (FBG) used in fiber lasers is an essential component of fiber lasers, which modulates the signal light in the fiber core through periodic refractive index modulation using ultraviolet exposure.

1560nm transmissive FBG fiber grating (AOS)

FBG stands for Fiber Bragg Grating, which stands for Fiber Bragg Grating. The essence of the grating with periodic spatial phase distribution formed inside the fiber core is to form a narrowband (transmission or reflection) filter or mirror inside the fiber core. By utilizing this characteristic, many high-performance fiber optic devices can be manufactured.

Tilted Fiber Bragg Grating

Tilted fiber Bragg grating is an advanced passive fiber optic device, whose internal refractive index modulation grating plane forms a specific angle (tilt angle) with the fiber axis. TFBG continuously couples the fundamental mode energy transmitted in the core to a series of different order cladding modes through its tilted refractive index modulation structure, while satisfying the phase matching condition.
