Abstract:
1. A multiplexing device for multiplexing a plurality of channels, wherein each channel contains light within a range of wavelengths, the multiplexing device comprising: a plurality of transmitters, each transmitter associated with one of the channels, wherein each transmitter provides a beam containing the associated channel; a plurality of optical alignment elements (OAEs), each OAE associated with one of the channels, wherein each OAE is configured to provide at least two directional changes in the path of the beam containing the associated channel; a plurality of filters, each filter associated with one of the channels, wherein each filter is transverse to the beam containing the associated channel and is configured to select a range of wavelengths which includes the associated channel; and an output element configured to receive the channels after the channels are selected by the associated filters.
