| Title: | Proposal and analysis of digital concatenated gratings | Authors: | He, X Huang, D Yu, Y Wang, D |
Issue Date: | 1-Jul-2008 | Source: | Journal of the Optical Society of America. A, Optics, image science, and vision, 1 July 2008, v. 25, no. 7, p. 1629-1633 | Abstract: | A digital concatenated grating composed of five subgratings is proposed. Essential formulas on Bragg periods of subgratings and an analytical expression for the reflection-spectrum envelope are presented, which show how to use reflection-spectrum envelopes to construct a digital concatenated grating with uniform reflection peaks. For a perfect design, the spectral center separation of adjacent Bragg gratings will be chosen as the integral times of the reflectivity peaks’ spacing. Gaussian apodization on the whole profile grating not only eliminates the sidelobes of each reflection peak but also provides a better flat reflection-spectrum envelope than that of the digital concatenated Gaussian-apodized grating. | Keywords: | Digital arithmetic Separation Trellis codes |
