Long-period waveguide gratings

Proceedings of the Sixth Chinese Optoelectronics Symposium (IEEE Cat. No.03EX701), 2004
Long period waveguide gratings (LPWG) based on a low-loss negative tone epoxy Novolak resin polymer have been fabricated on SiO/sub 2//Si substrate using standard cleanroom processes: UV photolithography and reactive ion etching. A maximum attenuation of -18 dB and a minimum 3 dB bandwidth of 6 nm were measured, and the grating length is as short as 1 ...

Long-period grating fabrication techniques

SPIE Proceedings, 2000
Electric discharge and CO2 laser exposure can produce long period gratings in standard telecommunication fibers. These two fabrication techniques are examined and compared to the UV laser exposure technique. Cladding modes involved in these gratings have been measured and identified using a computer simulation based on coupled mode equations ...

Optical fiber long-period grating sensors

Optics Letters, 1996
We present a novel class of highly sensitive sensors based on long-period fiber gratings that can be implemented with simple and inexpensive demodulation schemes. Temperature, strain, and refractive-index resolutions of 0.65 degrees C, 65.75 micro, and 7.69 x 10(-5), respectively, are demonstrated for gratings fabricated in standard telecommunication ...
