Abstract
Methods, apparatus, and systems for altering refractive index of an expanded beam connector lens include receiving signals from an expanded beam connector, detecting 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 an expanding lens included in the expanded beam connector.
Claims20
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.
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.
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.
