Summary:To provide a compact WDM filter with multi-channel capability.SOLUTION: The present invention provides a WDM filter component having a first port for inputting and outputting light of multiple wavelengths and a second port for inputting and outputting light of at least one of the multiple wavelengths. In a cross-section of a GRIN lens, the first port is located at a position different from the center axis of the GRIN lens.SELECTED DRAWING: Figure 1 【課題】本開示は、小型で多チャンネル化の可能なＷＤＭフィルタを提供することを目的とする。【解決手段】本開示は、複数の波長の光を入出力する第１のポートと、前記複数の波長のうちの少なくともいずれかを入出力する第２のポートと、を備えるＷＤＭフィルタ部品であって、前記第１のポートが、ＧＲＩＮレンズの断面のうちのＧＲＩＮレンズ中心軸とは異なる位置に配置されている、ＷＤＭフィルタ部品である。【選択図】図１
