Channel management

An optical communications method comprising:

• determining a first priority level of first data to be sent as first optical signals via a meta-waveguide having a limited quantity of channels;
• determining a second priority level of second data to be sent as second optical signals via the meta-waveguide;
• determining a first subset of the channels via which to send the first data;
• determining a second subset of the channels via which to send the second data;
• reserving a gap comprising unutilized channels between the first subset and the second subset of the channels depending on the first and the second priority levels;
• sending the first signals via the first subset of the channels;
• and
• sending the second signals via the second subset of the channels.

An advanced driver assistance system (ADAS), comprising:

• a memory device;
• a plurality of automotive data sources;
• a meta-waveguide comprising a plurality of channels coupled to the memory device;
• and
• a controller coupled to the memory device, the plurality of automotive data sources, and to the meta-waveguide, wherein the controller is configured to:
• determine a priority level of data received from the plurality of automotive data sources;
• reserve a gap comprising at least one unutilized channel between a first channel used to exchange a first type of data with the memory device and a second channel used to exchange a second type of data with the memory device, depending on a first priority level of the first type of data and a second priority level of the second type of data;
• exchange the first type of data with the memory device via the first channel;
• and
• exchange the second type of data with the memory device via the second channel.
