Abstract:
An optical device for use with at least one optical signal, each optical signal having a wavelength within a unique wavelength band, the optical device comprising:at least three transceiver elements, each transceiver element being operatively coupled to a lensing element, and each transceiver element emitting at least one of the optical signals, receiving at least one of the optical signals, or both; a filter subassembly having at least one prism, each prism having at least one substantially flat face, each prism being formed from a glass material; and at least one interference filter, each one of the interference filters being respectively deposited on one of the substantially flat faces of one of the prisms, each interference filter being selective between two of the unique wavelength bands of the optical signal; and a transparent mounting structure formed from a polymeric material, the transparent mounting structure having at least one transceiver element alignment feature, each transceiver element being held in one of the transceiver element alignment features, and a filter subassembly alignment feature, the filter subassembly being held in the filter subassembly alignment feature; wherein each optical signal is coupled from one of the transceiver optical elements to another of the transceiver optical elements by at least one of the interference filters, and wherein each lensing element is formed directly in the transparent mounting structure.
