Abstract
Official abstract text for this publication.
Methods, apparatus, and systems for cooling optical interconnects using light include monitoring an output power of a transceiver, where the transceiver includes an alkali activated geopolymer (AAGP) coating, and cooling, based on a determination that the output power has decreased below a threshold value, the transceiver by directing infrared light towards the transceiver.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method for cooling optical interconnects using light, comprising: monitoring an output power of a transceiver, wherein the transceiver includes an alkali activated geopolymer (AAGP) coating; and cooling, based on a determination that the output power has decreased below a threshold value, the transceiver by directing infrared light towards the transceiver. 2 . The method of claim 1 , wherein the infrared light is directed towards the transceiver from an infrared device. 3 . The method of claim 2 , wherein the infrared device is configured to direct the infrared light towards multiple transceivers. 4 . The method of claim 1 , wherein the infrared light is directed towards the transceiver from multiple angles via multiple infrared devices. 5 . The method of claim 1 , wherein the transceiver is cooled based on the infrared light and the AAGP coating. 6 . The method of claim 1 , wherein cooling the transceiver includes lowering the output power of the transceiver. 7 . The method of claim 1 , wherein the infrared light is directed towards the transceiver for a predetermined amount of time. 8 . The method of claim 1 , wherein the infrared light is directed towards the transceiver until the output power increases above the threshold value. 9 . The method of claim 1 , wherein the infrared light is directed towards the transceiver until a temperature of the transceiver falls below a threshold temperature. 10 . The method of claim 1 , wherein cooling the transceiver by directing the infrared light towards the transceiver is carried out based on a monitored error rate for the transceiver. 11 . A system for cooling optical interconnects using light, the system comprising: a transceiver including an alkali activated geopolymer (AAGP) coating; an infrared device; and a computer processor configured to: monitor an output power of the transceiver; and cool, based on a determination that the output power has decreased below a threshold value, the transceiver by the infrared device directing infrared light towards the transceiver. 12 . The system of claim 11 , further comprising multiple transceivers. 13 . The system of claim 12 , wherein the infrared device is configured to direct the infrared light towards the multiple transceivers. 14 . The system of claim 11 , further comprising multiple infrared devices, wherein the infrared light is directed towards the transceiver from multiple angles via the multiple infrared devices. 15 . The system of claim 11 , wherein the transceiver is cooled based on the infrared light and the AAGP coating. 16 . The system of claim 11 , wherein cooling the transceiver includes lowering the output power of the transceiver. 17 . The system of claim 11 , wherein the infrared light is directed towards the transceiver for a predetermined amount of time. 18 . The system of claim 11 , wherein the infrared light is directed towards the transceiver until the output power decreases below the threshold value. 19 . The system of claim 11 , wherein the infrared light is directed towards the transceiver until a temperature of the transceiver falls below a threshold temperature. 20 . The system of claim 11 , wherein cooling the transceiver by directing the infrared light towards the transceiver is carried out based on a monitored error rate for the transceiver.
