title = "A design method for a ratiometric wavelength monitor using a pair of directional couplers acting as edge filters",
abstract = "An integrated ratiometric wavelength monitor is proposed and designed, which consists of a Y-branch and two directional couplers acting as edge filters with opposite spectral responses. With a local supermodes solution, the optimal separation distance between two waveguides and the interaction length of the directional coupler are obtained to meet the desired spectral response with significantly less computation time by comparison to a parameter-space scanning method. The wavelength discrimination ability of the designed ratiometric structure is demonstrated numerically.",
