Abstract: System for coupling light to integrated devices, comprising a grating coupler which couples light, such as light from a light source, into an optic fiber. The system includes an optic subsystem comprising a transmitter portion receiving the light emitted by the grating coupler and a receiver portion receiving light from the transmitter and focusing the light into the integrated device, the transmitter portion being configured to modify an angle distribution of the light emitted by the grating coupler and the receiving portion being configured to focus the light with modified angle distribution into the integrated device.
