| 中文摘要 | bloch modes can be excited in planar array due to its periodic lateral refractive index. the power coupled into each eigenmode of the array waveguides is calculated through the overlap integrals of the input field with the eigenmode fields of the coupled infinite array waveguides projected onto the x-axis. low losses can be obtained if the transition from the array to the free propagation region is adiabatic. due to the finite resolution of lithographic process the gap between the waveguides will stop abruptly, however, when the waveguides come into too close together. calculation results show that losses will occur at this discontinuity, which are dependent on the ratio of the gap between the waveguides and grating pitch and on the confinement of field in the array waveguides. tapered waveguides and low index contrast between the core and cladding layers can lower the transmitted losses. |
