US Patent 11585991 Fiberless co-packaged optics

An electro-optical system, and method for making the electro-optical system. The electro-optical system includes a Photonic Integrated Circuit (PIC) having a laser source located on the PIC, a fiberless optical coupler located on the PIC. The fiberless optical coupler is configured to be coupled to a fiber array. The electro-optical system also includes an optical element, and a mechanical aligner. The optical element is aligned with the fiber array, via the mechanical aligner, for a light from the laser source to transmit in between the fiber array and the PIC through the optical element, when the fiberless optical coupler is coupled to the fiber array.
