Abstract
Bragg grating recorded in PTR glass could have large aperture and long length which enables the engineering of local Bragg elements in 3D. It is well known that holograms encode phase information through relative local phase shifts of the gratings created by the interfering beams. For uniform reflecting Bragg grating adding a 𝜋 phase-shift modifies the element's properties, creating a transmission notch at the Bragg wavelength. Here we investigate a new optical element which combines a transversely chirped Bragg grating with incorporated phase shift. This element operates as a wavelength-tunable transmission notch filter and could have applications in lasers and spectroscopy.
