Abstract:
1. An apparatus, comprising: a semiconductor chip; a turning mirror on the semiconductor chip which is tilted at a specified angle relative to the semiconductor chip, wherein the turning mirror is configured to direct optical signals from an optical fiber onto one or more first optical channels located on the semiconductor chip, wherein the one or more first optical channels have dimensions that are within a specified tolerance of the dimensions of the optical fiber; and wherein the turning mirror is configured to simultaneously couple multiple wavelengths of substantially surface-normal light with respect to the semiconductor chip to substantially in-plane light with respect to the semiconductor chip; one or more optical couplers configured to direct the optical signals from the one or more first optical channels to one or more second optical channels located on the semiconductor chip, wherein the one or more second optical channels have a specified sub-micron size; and one or more nano-lens structures each including a number of comb fingers, wherein the comb fingers are configured with a predetermined separation between the comb fingers so that the nano-lens structure has an average refractive index of the comb fingers, and wherein the nano-lens structure is configured to direct the optical signals from the one or more first optical channels to one or more second optical channels located on the semiconductor chip.
