    • An embodiment of the invention relates to an optical component (10, 300) for processing optical signals comprising a rhombic prism (20) having a first surface (SF1), a second surface (SF2) that is parallel to the first surface (SF1), a third surface (SF3) that is angled relative to the first and second surfaces (SF1, SF2) and connects the first and second surfaces (SF1, SF2), and a fourth surface (SF4) that is parallel to the third surface (SF3) and connects the first and second surfaces (SF1, SF2), wherein the third surface (SF3) is covered by a polarization dependent layer (PDL) capable of transmitting radiation having a first polarization and capable of reflecting radiation having a second polarization, said first and second polarizations being perpendicular to each other.
    • 本发明的实施例涉及一种用于处理光信号的光学部件(10,300),其包括具有第一表面(SF1)的菱形棱镜(20),与第一表面(SF1)平行的第二表面(SF2) 相对于第一和第二表面(SF1,SF2)成角度并连接第一和第二表面(SF1,SF2)的第三表面(SF3)和平行于第三表面的第四表面(SF4) SF3)并且连接第一和第二表面(SF1,SF2),其中第三表面(SF3)被能够透射具有第一偏振的辐射并且能够反射具有第二偏振的辐射的偏振相关层(PDL)覆盖, 所述第一和第二极化彼此垂直。
