“…It is very hard for the air-bearing translation stage to hold its position within nano-meters scale range for a certain period of time. That is the main reason that other methods used constant velocity while synchronizing the shutter for the purpose of minimizing the phase errors during writing [9,10]. Keeping the position of the stage within as small as ± ~3-nm is impossible without proper environmental isolation and fine-tuning of the air-bearing translation stage.…”

Abstract:We proposed and demonstrated a novel practical fiber Bragg grating (FBG) fabrication setup constructed with high performance linear stages, piezoelectric translation (PZT) stages, and a highly stable continuous wave laser. The FBG fabrication system enables writing of long FBGs by a continuous translate-and-write process and allows implementation of arbitrary chirp and apodization. A key innovation is that the local Bragg wavelength is controlled by a simple movement of the phase mask by a PZT in the direction perpendicular to its surface. The focus position of the two writing beams is not changed during the Bragg wavelength change, an intrinsic feature of the design, ensuring simplicity, robustness and stability. Apodization can be achieved by vibrating the phase mask in the direction parallel to its surface by a PZT. Phase steps can also be inserted in FBGs at any desired locations by stepping the same PZT. A long uniform FBG and a linearly chirped FBG are written to demonstrate the performance of the setup.

“…Mechanical methods were used to control the optical phase via piezo actuators, and the angle of incidence with stepper motors [8]. Individual phase masks were used in [9][10][11], which inevitably limits the flexibility and simplicity of the grating manipulation. In reference [9], an external signal was used to amplitude modulate the writing beam while the fiber was continuously translated.…”

A direct UV grating writing technique based on phase-controlled interferometry is proposed and demonstrated in a silica-on-silicon platform, with a wider wavelength detuning range than any previously reported UV writing technology. Electro-optic phase modulation of one beam in the interferometer is used to manipulate the fringe pattern and thus control the parameters of the Bragg gratings and waveguides. Various grating structures with refractive index apodization, phase shifts and index contrasts of up to 0.8 × 10 −3 have been demonstrated. The method offers significant time/energy efficiency as well as simplified optical layout and fabrication process. We have shown Bragg gratings can be made from 1200nm to 1900nm exclusively under software control and the maximum peak grating reflectivity only decreases by 3dBover a 250 nm (~32THz) bandwidth.

A simple and wavelength-flexible procedure for fabricating phase-shifted fibre Bragg gratings

A simple procedure for fabricating phase-shifted fibre Bragg gratings (PSFBGs) that does not require the use of a phase-shifted phase mask is presented. Two standard fibre Bragg gratings (FBGs) of equal length and with the same Bragg wavelength are inscribed sequentially in single mode optical fibre, such that the FBGs overlap physically by one grating period. This procedure induces a spectral-hole in the middle of the reflection spectrum, equivalent to a -phase shifted FBG. PSFBGs have been fabricated in the 1300 nm and 1550 nm wavelength bandwidths, demonstrating flexibility in the choice of the centre wavelength. The PSFBGs fabricated are compared with a model based on a modified Rouard's method which is subsequently used to investigate the influence of translation stage errors on the fabrication of the PSFBGs. The model demonstrates that the strength/reflectivity of the PSFBG influences the spectral-hole linewidth as well as the finesse of the device while the length of the PSFBG affects only the linewidth of the spectral-hole but not the finesse of the device. The PSFBG devices produced by this technique are reproducible and the fabrication process is fast and is well suited for the fabrication of WDM PSFBGs.
