Abstract
A robust and rugged method for sensing atoms and molecule using a small hybrid Hollow-Core Photonic Bandgap Fiber (HCPBF) is described. The hybrid fiber and associated chamber apparatus is amenable to mass production and can be used for wavelengths of light from 400 nm to 2000 nm.
Claims8
A method for constructing a HCPBF chamber, the method comprising of the steps of:
- a) splicing a segment of HCPBF to a solid core fiber at each distal end;
- b) creating a gap in the segment of HCPBF;
- c) mounting the gapped HCPBF segment in a permanent manner;
- d) securing the mounted gapped HCPBF segment in a chamber in a permanent fashion;
- e) hermetically sealing the chamber;
- and
- f) fixing a sealable port in the chamber wall, wherein no light is generated by construction of the HCPBF chamber.
