| 摘要 |
<p>The invention relates to an optical arrangement, in particular for bi-directional WDM systems with at least three wavelengths, comprising at least one Mach-Zehnder interferometer (I) with a first arm and a second arm and at least one directional coupler with a first arm (11) and a second arm (12). According to the invention, at least one Mach-Zehnder interferometer (1) and at least one directional coupler (2) are interleaved such that one arm (12) of the Mach-Zehnder interferometer (1) simultaneously forms one of the arms (21) of the directional coupler (2), or vice versa. The invention further relates to a transceiver module with such an optical arrangement.</p> |
