dc.description.abstract	We use the coupled-mode theory to analyze the transmission spectra of a coupler consisting of two parallel uniform or non-uniform long-period waveguide gratings (LPWGs) and highlight the conditions for achieving 100% coupling efficiency with uniform LPWGs. We also investigate the effects on the transmission characteristics of the coupler due to various forms of non-uniformity along the LPWGs. LPWG couplers can be used to realize stable and efficient broadband add/drop multiplexers and serve as building blocks of new waveguide-based coupling devices.	en
