Abstract

We present separation of fibre Bragg grating wavelength reflections in a multicore fibre with an even peak wavelength distance between reflections in the multiple cores of a single cross-section plane. The inscription is achieved simultaneously in all cores by applying a bend in the fibre, and thus inducing a different variation of the effective refractive index in each core. Such method for wavelength multiplexing would enable the interrogation of multiple sensors signals delivered by a single channel, e.g., without the need of a fanout device or a multichannel spectrometer.
