Low Loss Optical Crossing and Method of Making Same |
| 摘要 |
A low loss optical crossing and a method of making an optical crossing in a photonic integrated circuit. An optical crossing embodiment includes a crossing region having a crossing length, wherein a light path through the crossing region is laterally unbound; an input waveguide having an input crossing end and an input distal end, and coupled to the crossing region at the input crossing end, thereby partially forming the light path; and an output waveguide having an output crossing end and an output distal end, and coupled to the crossing region at the output crossing end, thereby partially forming the light path, wherein a crossing width of the output waveguide at the output crossing end is larger than a crossing width of the input waveguide at the input crossing end according to the crossing length, and wherein a lateral center of the output waveguide at the output crossing end is laterally displaced by an offset from a lateral center of the input waveguide at the input crossing end according to the crossing length. |

1. A photonic integrated circuit (PIC) having an optical crossing, comprising:
a crossing region having a crossing length, wherein a light path through the crossing region is laterally unbound; an input waveguide having an input crossing end and an input distal end, and coupled to the crossing region at the input crossing end, thereby partially forming the light path; and an output waveguide having an output crossing end and an output distal end, and coupled to the crossing region at the output crossing end, thereby partially forming the light path, wherein a crossing width of the output waveguide at the output crossing end is larger than a crossing width of the input waveguide at the input crossing end according to the crossing length, and wherein a lateral center of the output waveguide at the output crossing end is laterally displaced by an offset from a lateral center of the input waveguide at the input crossing end according to the crossing length. |
