Enhanced light extraction of C-band on-chip LED by photonic crystals for arrayed waveguide grating demodulation integrated microsystems
Fiber Bragg grating sensors are widely known to have had great progress. These sensors have been used to measure strain, temperature, pressure, and other physical quantities that can be converted into strain or temperature . However, the traditional fiber grating demodulation system is large and expensive, and its application field is limited.
