A coupler having fewer individual parts improves manufacturability and scalability. The coupler includes a wavelength selective filter, a first port for propagating at least a first wavelength, a second port for propagating at least a second wavelength different from the first wavelength, and a third port for propagating at least the first wavelength and the second wavelength. The three ports are positioned relative to the wavelength selective filter. At least two individual optical elements are also included in the coupler. Each optical element is associated with one of the three ports, between an associated port and the wavelength selective filter. All optical elements needed for directing light between the ports and the wavelength selective filter are provided on at least one of a substrate and substrates bonded thereto.
