| 中文摘要 | a wavelength division multiplexer (wdm) for 980/1550 nm based on planar curved waveguide coupler (cwc) is proposed. compared with conventional parallel straight waveguide coupler (swc), this structure has more flexibility with two variable parameters of bending radius r and minimum edge-to-edge spacing do, which are the two main parameters for the splitting ratio of coupler and decrease the complexity of device design and fabrication. based on coupled mode theory (cmt) and waveguide theory, r and do of the wdm cwc are designed to be r = 13.28 m and d(0) = 4.39 mu m. the contrast ratio (cr) and insertion loss (il) for 980 and 1550 nm are cr1 = 24.62 db, cr2 = 24.56 db and il1 = 0.014 db, il2 = 0.015 db, respectively. the 3d beam propagation method (bpm) is used to verify the validity of the design result. the influence of r and d(0) variations on the device performance is analyzed. for cr > 20 db, the variation ranges of r and d(0) should be within -0.10 to +0.44 m and -0.05 to + 0.02 mu m, respectively.
