Abstract
Method and multiport free-space wavelength division multiplexing ('WDM') device capable of handling multiple optical signals carried in multiple wavelengths ('λ') using a relay lens are disclosed. The WDM device includes an optical filter, collimator, optical relay, and a relay optical filter. The optical filter is able to receive an optical beam containing multiple λand subsequently extract a first wavelength (“λ”) from λ. A second optical beam is formed by the remaining of λ. The collimator, in one example, receives λfrom the optical filter. Upon receiving the second optical beam, the optical relay collimates the second optical beam with minimal loss due to light divergence. The relay optical filter, in one aspect, is configured to receive the collimated second optical beam and redirects the collimated second optical beam to a predefined intended orientation.
