METHOD AND APPARATUS FOR WAVELENGTH DIVISION MULTIPLEXING

摘要

An apparatus and method of Wavelength Division Multiplexing (WDM) are provided. The WDM multiplexer (500) includes a plurality of lasers (520), a plurality of collimating lenses (540) and a single focusing lens (560). Each lens of the plurality of lenses (540) is positioned so as to collimate a beam of light emitted by a laser of the plurality of lasers (540). The focusing lens (560) is positioned to focus a plurality of collimated beams of light received from the plurality of lenses (540) into substantially a point of light (580). The WDM multiplexer (500) includes a receptacle (550) that houses the plurality of lasers (520), the plurality of collimating lenses (540) and the focusing lens (560).
