Abstract
An integrated grating coupler system includes a first chip having a first substrate, a first grating structure formed by first grating curves arranged on the first substrate and a cladding layer formed to cover the first grating structure, wherein the first chip include a first waveguide configured to receive a light beam from a first end via the first waveguide and transmit the light beam through a second end, a second chip having a second substrate and a second grating structure formed by second grating curves arranged on the second substrate, wherein the second chip is configured to receive the light beam from the second end of the first chip and transmit the light beam from an end of the second chip, and a common block configured to mount the first chip and second chip via a first submount and a second submount respectively, wherein the first and second submounts are arranged such that the light beam from the second end of the first chip is received at a top of the second chip.
