发明名称 Reducing amplitude errors in arrayed waveguide gratings
摘要 An arrayed waveguide grating with improved edge channel aberration may be achieved by tuning the arrayed waveguide grating to have a stigmatic point for the input and output waveguides that is not at the center of the Rowland circle. In this way, crosstalk, ripples, and transmission spectrum uniformity may be improved in some embodiments of the present invention.
