Abstract
An apparatus includes a cladding layer and a plurality of waveguides. The cladding layer includes a central axis. The plurality of waveguides are disposed within the cladding layer and receive a light from a light source. The plurality of waveguides have refractive indices that are adjustable to change a mode of the light such that the mode of the light is steered towards the central axis.
Claims14
An apparatus comprising:
- a cladding layer comprising a central axis;
- and
- a plurality of waveguides disposed within the cladding layer and configured to receive a light from a light source, the plurality of waveguides comprising electrical contacts arranged to receive an electrical signal, wherein the electrical signal adjusts refractive indices of the plurality of waveguides such that the plurality of waveguides redirect a mode of the light towards the central axis.
A method comprising:
- sending one or more electric signals to electrical contacts of a plurality of waveguides disposed within a cladding layer to adjust refractive indices of the plurality of waveguides;
- and
- redirecting, by the plurality of waveguides, a mode of a light from a light source towards a central axis of the cladding layer.
An apparatus comprising:
- a substrate;
- a bottom oxide layer disposed on the substrate;
- a cladding layer disposed on the bottom oxide layer, the cladding layer comprising a central axis;
- a plurality of waveguides disposed within the cladding layer and configured to receive a light from a light source, the plurality of waveguides arranged to receive heat energy, wherein the heat energy adjusts refractive indices of the plurality of waveguides such that the plurality of waveguides redirect a mode of the light towards the central axis;
- and
- a central waveguide disposed within the cladding layer beneath the plurality of waveguides, the plurality of waveguides further configured to change the mode of the light such that the mode of the light is steered towards the central waveguide.
