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.
产品特点Multi mode coupling effect, high refractive index sensitivity, multi parameter synchronous measurement
