Volume Holographic Grating Filters (VHG)

…(VHG) All Coherent Volume Holographic Grating Filters (VHGs) are bulk “solid-state” diffractive holographic filters made from a proprietary photosensitive optical glass, which unlike thin films or gels, can deliver ultra-stable, degradation free performance over an unlimited lifetime. Capable of…

…the fibers, a Q-Switched CO2 or UV laser e.g. AVIA applies. The open fiber structure enables higher shear strength after welding, as the molten thermoplast of the other welding partner flows around and in between the fibers.

…optical fibers is doped
with germanium (to increase the refractive index), which makes it photosensitive in the ultraviolet (UV). Specifically,
photosensitivity means that exposure to
UV light will induce a permanent refractive-index change. In some cases, photosensitivity is created…

4.1 Systems for flexible phase mask writing of FBGs
FBG fabrication usually occurs via the phase mask
method exposing a photosensitive fiber to an interference
fringe pattern created by a phase mask. Directing the excimer laser beam through a phase mask the latter diffracts…

…ranging from Raman spectroscopy sources to fiber optic communications links. Traditional diode based ECL technologies rely on surface gratings (ruled or holographic) or on Bragg gratings located within the optical fiber (commonly referred to as Fiber Bragg Gratings or FBGs). These techniques have…
