Phase Mask for Fiber Bragg Grating

We produce phase masks of up to 150mm in length for fiber Bragg grating fabrication.  Our phase mask products include uniform, chirped, phase shift, long phase mask and sample phase masks for DWDM filter, dispersion compensation, gain flattening, laser diode stabilizer, waveguide and sensor applications.  Our products cover a wide range from 500nm to 5000nm in grating period.  Our unique fabrication technique guarantees an ultra high precision period, a very low zero order and a very high uniformity.

There are several Phase Mask Types:

Multi Phase Mask Array   for DWDM Fiber Grating Filter Fabrication

Multi Phase Shift Phase Mask   for up to 300 Phase Shifts in a Single Phase Mask

Multi Position Phase Mask   for Sensor, Waveguide and Multi Wavelength FBG Fabrication

Chirped Phase Mask  for Linear Chirp, Nonlinear Chirp, Sinusoid Chirp Fiber Grating Fabrication

Long Phase Mask  up to 150mm long phase mask with all different types

Features:

  • Period accuracy to 1 pm
  • Zero order < 3% ( typical ),  <1% ( minimum ), < 5% ( maximum )
  • Length up to 150 mm
  • Period down to 100nm
  • Uniform, chirped, phase shift
  • Optimized for 193 nm, 244nm, 248 nm, 266 nm 325nm, 365nm UV illumination
  • Affordable prices

New Phase Mask Products:

1. Multi Phase Mask Array   is used for making DWDM Fiber Grating filter with 4 channel, 8 channel, or 16 channels.  It features in one substrate with 2, 4, 8, 16 phase masks with different periods. The Multi Phase Mask Array  makes the setup of fiber grating fabrication very simple. Without changing the phase mask, 4 to 16 channels of fiber grating filters can be made in one setup.  It also can save the time and money for our customers to buy only one phase mask instead of several phase masks. 

2. Multi Phase Shift Phase Mask   is a phase mask with up to 200 phase shifts. It gives a fiber optics engineer a great freedom of phase mask design. The multi phase shift can be incorporated with chirped phase mask and uniform phase mask or combination of both.

 3. Multi Position Phase Mask   is a phase mask array in horizontal, vertical or both. For example, each of an array of fiber Bragg gratings should be positioned with high precision along a fiber for sensor application, the Multi Position Phase Mask   can remove the alignment problem between each phase mask and the fiber and provides you with the best solution. If you want to make multi wavelength fiber laser, the Multi Position Phase Mask  can also make your job much easier in this fiber laser fabrication process.
