Abstract
Fiber optic devices including volume Bragg grating (VBG) elements are disclosed. A fiber optic device may include one or more optical inputs, one or more VBG elements, and one or more optical receivers. Methods for manufacturing VBG elements and for controlling filter response are also disclosed. A VBG chip, and fiber optic devices using such a chip, are also provided. A VBG chip includes a monolithic glass structure onto which a plurality of VBGs have been recorded.
Claims14
A method for manufacturing a Bragg grating element, the method comprising:
- forming a Bragg grating wafer having a Bragg grating recorded therein, said Bragg grating being characterized by a grating wave vector;
- and
- segmenting the Bragg grating wafer into a plurality of individual Bragg grating elements, wherein each of the individual Bragg grating elements retains the grating wave vector of the Bragg grating wafer.
