Abstract: A wavelength division multiplexing device includes a common port and a plurality of filters that define an optical path. The common port includes a collimator that transmits an optical beam including a plurality of optical signals. Each optical signal is associated with a different wavelength range, and each filter includes an interface having a radius of curvature. One filter is configured to receive the optical beam from the collimator, transmit an optical signal through its interface, and reflect the remaining portion of the optical beam toward another filter. The common collimator and filter are configured so that the reflected portion of the optical beam has a beam waist located in the optical path midway between the filters, and a wavefront radius of curvature at the other filter that matches the filter radius of curvature of that filter. A method of processing light in such a device is also disclosed.
