Abstract: High density fiber interfaces for silicon photonics based integrated-optics products are provided via a system or device that includes: a prism configured to reflect, via a lensed reflecting surface, a plurality of optical signals between a first surface and a second surface at a non-normal angle of incidence; a photonic interposer including a plurality of grating couplers corresponding to the plurality of optical signals that are arranged in a two-dimensional array and that are optically connected directly to the first surface of the prism; and a plurality of optical fibers that are arranged in the two-dimensional array and that are optically connected directly to the second surface of the prism.
