| Abstract: | Long period gratings (LPGs) are fabricated by use of focused high frequency CO₂ laser pulses to periodically modify the transverse dimension of silica microfibers. A 20-period LPG with a 27dB attenuation dip is realized in a microfiber with a diameter of ~6.3μm. The resonant wavelength has a negative temperature coefficient and a high sensitivity to external refractive index. The microfiber LPGs may be useful in micron scale in-fiber devices and sensors. |
