Abstract :
Hollow core antiresonant fibers offer new possibilities in the near infrared and visible spectral range. I show here that the great flexibility of this technology can allow the design and fabrication of hollow core optical fibers with an extended transmission bandwidth in the near infrared and with very low optical attenuation in the visible wavelength regime. A very low attenuation of 175 dB/km at 480 nm is reported. A modification of the design of the studied fibers is proposed in order to achieve fast-responding gas detection.
