Abstract
Exemplary multi-channel optical couplers include a molded coupling module comprising a first surface, a second surface, a lens array receptacle, and fiber receptacles for optical fibers; an optical arrangement comprising: a particular surface carrying a reflective coating, and a further surface carrying a plurality of optical filters, each configured to pass a single optical wavelength; a first lens array configured such that each lens is optically aligned with the plurality of optical filters via at least the reflective coating, and with a position, within a particular fiber receptacle, corresponding to the end of a particular optical fiber; a second lens array arranged with the second surface such that each lens is optically aligned with an optical filter. The optical block and lens arrays can be configured such that the optical coupler produces no more than −10 dB of crosstalk on any of the optical wavelengths passed by the optical filters.
