“…wavelength and intensity) are strongly dependent on the grating period and the refractive index modulation that occurs on the fiber material [4,5]. If FBGs with different reflection wavelengths and reflectivities are inscribed in the fiber channels, it then becomes possible to distinguish between the different fiber channels using their reflection signals [6][7][8][9]. Recently, the FBGs Co. has proposed and implemented optical channel identification technology based on these gratings [10].…”

Optical fibers are typically used in telecommunications services for transmission of data, fiber tags are essential to distinguish between different transmission fibers or channels to ensure the working functions of the communication system. Traditional physical entity marking method for fiber labelling is bulk in size, easy confusion and most importantly the label information can be easilly accessed by all potential users. In this work, we propose an encrypted optical fiber tag based on encoded fiber Bragg grating array fabricated by a pointby-point femtosecond laser pulse chain inscription method. Gratings with different resonant wavelengths and reflectivities can be achieved by adjusting the grating period and refractive index modulations. It is demonstrated a binary data sequence carried by a fiber tag can be inscribed into the fiber core in the form of FBG array, and the data can be encryted by proper design of the spatial distributions of FBGs with varing reflection wavelengths and reflectivities.The proposed fiber tag technology could be used for port identification, encrypted data storage and transmission in fiber networks.

“…The most spread method for inscription of uniform and nonuniform grating is the method of direct writing through a phase mask [1]. This technique has made possible the development of a vast range of devices, such as distributed feedback fiber lasers [2,3], optical narrowband filters [4], optical code division multiple access en/decoders [5,6], multiplexers/demultiplexers [7] and so on, that are based on, for example, phase-shifted gratings [8] and sampled gratings [9][10][11]. In this paper, we present a modified methodology previously demonstrated in [12], where a direct acoustic modulation of the fiber is used, however using only the set of the acoustic burst time characteristics.…”

The inscription of customized fiber Bragg structures under acoustic excitation is proposed and demonstrated. By setting the proper acoustic excitation function, the desired spectrum of the grating can be achieved. In this paper, the effect of applying a burst acoustic wave during the process of Bragg grating inscription using the direct writing method through a phase mask is investigated. Among all the characteristics that can be changed due to a periodic defect insertion in the uniform Bragg structure, the control of phase is used to demonstrate this assertion. The results of numerical simulations are shown to be in excellent agreement with experiments. It can be further extended to generate multiple phase shifts in optical fiber and/or waveguides, if the defects are inserted at different positions, as is shown.

“…There have been several O-CDMA schemes including time, wavelength or space domain encoding/decoding procedures [2]. Among these, time-spreading/wavelength-hopping two-dimensional (2-D) codes utilizing both time and wavelength domain encoding/decoding are receiving increasingly more attention because of their superior spectral efficiency compared to direct sequence codes and flexible coding [3,4]. Recently, an arrayed waveguide grating router-based O-CDMA codec was proposed [5].…”

We propose a simply tunable optical codec using a cyclic wavelength shifter, which can be applied for two-dimensional optical CDMA (O-CDMA) schemes. The cyclic wavelength shifter is based on dual-band holographic grating. By using this device, it is easy to implement various optical CDMA codecs utilizing constant-weight cyclic-permutable codes. In this paper, the basic principle and the feasibility of the proposed device is demonstrated experimentally. (
