Altering refractive index of an expanded beam connector lens

1 . A method for altering refractive index of an expanding lens, the method comprising:

receiving signals from an expanded beam connector;

detecting, by a sensor associated with the expanded beam connector, a decibel loss of the signals in the expanded beam connector that exceeds a loss threshold; and

directing, via a transmitter included in the expanded beam connector and in response to detecting the decibel loss, light at the expanding lens included in the expanded beam connector,

wherein the light is directed at the expanding lens to alter the refractive index of the expanding lens by:

increasing absorption of ultraviolet light by the expanding lens, or

changing a temperature of the expanding lens.

2 . The method of claim 1 , further comprising determining whether the decibel loss has changed based on the directed light.

3 . The method of claim 2 , further comprising, if the decibel loss has decreased responsive to directing the light but remains above the loss threshold: again directing, via the transmitter, the light at the expanding lens until the decibel loss has decreased below the loss threshold.

4 . The method of claim 2 , further comprising, if the decibel loss has increased, stopping directing of light to the expanding lens.

5 . The method of claim 2 , further comprising, if the decibel loss has not changed, again directing, via the transmitter, the light at the expanding lens until the decibel loss has changed.

6 . The method of claim 1 , wherein the loss threshold is specific to the expanded beam connector.

7 . The method of claim 1 , wherein the expanding lens comprises a germanium-doped glass.

8 . The method of claim 7 , wherein the light directed at the expanding lens comprises ultraviolet light.

9 . The method of claim 1 , wherein the light directed at the expanding lens comprises infrared light.

10 . A system for altering refractive index of an expanding lens, the system comprising:

a silicon chip; and

an expanded beam connector coupled to the silicon chip, wherein the expanded beam connector includes:

the expanding lens; and

a transmitter;

wherein the system is configured to:

transmit, by the expanded beam connector, signals to the silicon chip;

detect, by a sensor of the silicon chip, a decibel loss of the signals in the expanded beam connector that exceeds a loss threshold; and

direct, via the transmitter and in response to detecting the decibel loss, light at the expanding lens,

wherein the light is directed at the expanding lens to increase absorption of ultraviolet light by the expanding lens to alter the refractive index of the expanding lens, or

wherein the light is directed at the expanding lens to change a temperature of the expanding lens to alter the refractive index of the expanding lens.

11 . The system of claim 10 , wherein the transmitter is positioned within the expanded beam connector and pointed towards the expanding lens.

12 . The system of claim 10 , wherein the silicon chip is further configured to determine whether the decibel loss has changed based on the directed light.

13 . The system of claim 12 , wherein the expanded beam connector is further configured to, if the decibel loss has decreased responsive to directing the light but remains above the loss threshold: again direct, via the transmitter, the light at the expanding lens until the decibel loss has decreased below the loss threshold.

14 . The system of claim 12 , wherein the expanded beam connector is further configured to, if the decibel loss has increased, stop directing the light to the expanding lens.

15 . The system of claim 12 , wherein the expanded beam connector is further configured to, if the decibel loss has not changed, again direct, via the transmitter, the light at the expanding lens until the decibel loss has changed.

16 . The system of claim 10 , wherein the loss threshold is specific to the expanded beam connector.

17 . The system of claim 10 , wherein the expanding lens comprises a germanium-doped glass.

18 . The system of claim 17 , wherein the light directed at the expanding lens comprises ultraviolet light.

19 . The system of claim 10 , wherein the light directed at the expanding lens comprises infrared light, and

wherein the infrared light changes the temperature of the expanding lens.

20 . An apparatus for altering refractive index of an expanding lens, the apparatus comprising:

a connector configured to couple to a silicon chip;

an expanding lens configured to expand a light signal for the silicon chip; and

a transmitter configured to direct light at the expanding lens responsive to detecting a decibel loss of the light signal that exceeds a loss threshold,

wherein the light is directed at the expanding lens to increase absorption of ultraviolet light or to change a temperature of the expanding lens, and

wherein the refractive index, of the expanding lens, is altered based on increasing the absorption of ultraviolet light or based on changing the temperature of the expanding lens.
