提出了一种采用倾斜光纤布拉格光栅（S-FBG）的新型光分插复用器（OADM）。S-FBG将导模耦合到辐射模，并且它们还将特定的辐射模耦合到导模。位于彼此附近的一组S-FBG用作OADM。来自光纤的输出光束通过倾斜光栅耦合到另一光纤。所提出的OADM不需要作为使用FBG的传统复用器的组件的光环行器。可以构造低成本和小尺寸的光学滤波器。计算结果成功地显示了OADM的可能性。
Novel optical add/drop multiplexers (OADMs) using slanted fiber Bragg gratings (S-FBGs) are proposed. The S-FBGs couple the guided mode to radiation modes, and they also couple specific radiation modes to the guided mode. A set of S-FBGs located near each other function as OADMs. Output light beams from an optical fiber couple to the other fiber by the slanted gratings. The proposed OADM does not require optical circulators that are components of conventional multiplexers using FBGs. Low-cost and small-size optical filters may be constructed. Calculation results successfully show the possibilities of OADMs.
