摘要	A wavelength division multiplexing device (10) comprises a homogeneous refractive index collimating lens (16) for collimating a plurality of monochromatic optical beams (28), a mirror (18a), a diffraction grating (20), for combining the plurality of collimated, monochromatic optical beams into a multiplexed, polychromatic optical beam (30), and a homogeneous refractive index lens L (22) for focusing the multiplexed, output beam. The WDM is connected via coupling devices (14, 24) to optical fiber (12, 16) or active devices like photodiodes or lasers. In a preferred embodiment, the lenses are made of a material having a high refractive index to keep spherical aberrations low. The WDM may also contain additional boot lenses made of lower refractive index material.
其他摘要	波分复用装置（10）包括用于准直多个单色光束（28）的均匀折射率准直透镜（16），镜子（18a），衍射光栅（20），用于组合多个准直，单色光束成为多路复用的多色光束（30），和均匀折射率透镜L（22），用于聚焦多路复用的输出光束。 WDM通过耦合装置（14,24）连接到光纤（12,16）或有源装置，如光电二极管或激光器。在优选实施例中，透镜由具有高折射率的材料制成，以保持较低的球面像差。 WDM还可以包含由较低折射率材料制成的附加引导透镜。
