Interrogation of Fibre Bragg Grating Sensors Using an Arrayed Waveguide Grating

We experimentally investigate the use of an arrayed waveguide grating (AWG) to interrogate fibre Bragg grating (FBG) sensors. A broadband light source is used to illuminate the FBG sensors. Reflected spectral information is directed to the AWG containing integral photodetectors providing 40 electrical outputs. Three methods are described to interrogate FBG sensors. The first technique makes use...

Interrogation of a long-period grating using a mechanically scannable arrayed waveguide grating and a sampled chirped fiber Bragg grating.

A novel technique to interrogate a long-period grating (LPG) using a mechanically scannable arrayed waveguide grating (AWG) is proposed. This technique is implemented based on space-to-wavelength mapping by mechanically scanning the input light beam along the input coupler facet of an AWG. By employing a sampled chirped fiber Bragg grating with multiple peaks as a reference, the central wavelen...

Arrayed Waveguide Grating Router

This paper discusses design, fabrication, and characterization of a 512 × 512 arrayed waveguide grating router (AWGR) with a channel spacing of 25 GHz. The dimensions of the AWGR is 16 mm × 11 mm and is fabricated on a 250 nm silicon-on-insulator platform. The measured channel crosstalk is approximately −4 dB without any compensation for the phase errors in the arrayed waveguides. The AWGR spec...

Time-division-multiplexed interrogation of fibre Bragg grating sensors using laser diodes

An intensity-based technique for the interrogation of fibre Bragg grating sensors is described. The technique utilizes two longitudinal modes of a single, pulsed laser diode as a dual-wavelength source for grating illumination. Time-division-multiplexed addressing of sensor arrays in serial and tree topologies is also demonstrated.
