Abstract
A system for optically aligning a photonics die to a fiber array, the fiber array comprising a first and a second fiber channels, the system comprising: the photonics die having: a first and a second optical channels; a first and a second wavelength division multiplexing (WDM) couplers each comprising a bar port, a cross port, and a common port, the first and the second WDM couplers being optically connected to the first and the second optical channels, respectively, via the bar ports and the common ports; and a waveguide crossing optically connecting the cross ports of the first and the second WDM couplers; the system being adapted to couple an optical signal received from the first fiber channel into the cross port of the first WDM coupler and into the waveguide crossing, the optical signal being propagated from the waveguide crossing into the cross port of the second WDM coupler.
