Abstract:
1. A Bragg grating chip, comprising: a monolithic, three-dimensional glass structure onto which a first Bragg grating has been recorded at a first location and a second Bragg grating has been recorded at a second location, wherein the first location and the second location are separated from one another in each of two perpendicular directions, wherein the first Bragg grating is adapted to receive incident light having a wavelength in a fiber optic range and to deflect a first portion of the received incident light to the second Bragg grating, wherein the first Bragg grating has a first period and a first wave vector, and wherein the second Bragg grating has a second period that is the same as the first period and a second wave vector that is the same as the first wave vector.
