Nvidia patents waveguide design with mixed rib structures for high power
Nvidia describes a waveguide, a tiny channel that guides light, featuring a central core rib and two outer ribs. The outer ribs have a different structure than the inner one to help the device handle high optical power.
In the filing’s own words
A waveguide includes an inner rib comprising a core of the waveguide. The waveguide further includes first and second outer ribs having at least one structural feature different from the inner rib.
What exactly they claim (claim 1)
1. A waveguide, comprising: an inner rib comprising a core of the waveguide; and first and second outer ribs having at least one structural feature different from the inner rib.
