Optical Interposer

摘要

An optical interposer comprising an array of first order diffraction grating couplers arranged to couple light emitted by an array of single mode Vertical-Cavity Surface-Emitting Lasers (VCSELs) into optical waveguides, the light being emitted in a direction substantially perpendicular to the optical waveguides; a device for refracting the light over at least 4 degrees; an array of output ports arranged to optically couple light from the optical waveguides into an array of optical fibers or other optical elements; and the optical waveguides connecting the array of first order diffraction grating couplers and the array of output ports to route the light from the diffraction gratings into the output ports.

1. An optical interposer comprising:
an array of first order diffraction grating couplers arranged to couple light emitted by an array of single mode Vertical-Cavity Surface-Emitting Lasers (VCSELs) into optical waveguides, said light being emitted in a direction substantially perpendicular to said optical waveguides; a device for refracting said light over an angle of at least four degrees from said substantially perpendicular direction wherein said light is emitted by said array of single mode VCSELs, said device being positioned between said array of single mode VCSELs and said array of first order diffraction grating couplers; an array of output ports arranged to optically couple light from said optical waveguides into an array of optical fibers or other optical elements; and said optical waveguides coupling said array of first order diffraction grating couplers to said array of output ports to route said light from said first order diffraction grating couplers to said output ports.
