Claims

1. An apparatus including:
a laser; and
an electrostatic discharge protector coupled to an anode of the laser, the electrostatic discharge protector capable of shunting excess current resulting from an electrostatic discharge away from the anode of the laser.
2. The apparatus of claim 1, wherein a modulation signal is coupled to the anode of the laser through the electrostatic discharge protector.
3. The apparatus of claim 1, wherein the electrostatic discharge protector is an integrated circuit.
4. The apparatus of claim 1, wherein the anode of the laser is wire bonded to an output of the electrostatic discharge protector.
5. The apparatus of claim 1, wherein the laser is a Vertical Cavity Surface Emitting Laser.
6. The apparatus of claim 1, wherein a cathode of the laser is coupled to the electrostatic discharge protector.
7. The apparatus of claim 1, further comprising:
an electrical physical layer driver having a positive terminal coupled to the electrostatic discharge protector, the electrical physical layer driver providing modulation current to the laser through the electrostatic discharge protector.
8. A method comprising:
providing electrostatic discharge protection for a laser by coupling an an electrostatic discharge protector to an anode of the laser; and
upon detection of an electrostatic discharge, shunting excess current resulting from an electrostatic discharge away from the anode of the laser.
9. The method of claim 8, wherein a modulation signal is coupled to the anode of the laser through the electrostatic discharge protector.
10. The method of claim 8, wherein the electrostatic discharge protector is an integrated circuit.
11. The method of claim 8, wherein the anode of the laser is wire bonded to an output of the electrostatic discharge protector.
12. The method of claim 8, wherein the laser is a Vertical Cavity Surface Emitting Laser.
13. The method of claim 8, wherein a cathode of the laser is coupled to the electrostatic discharge protector.
14. The method of claim 8, further comprising:
providing modulation current to the laser from an electrical physical layer driver coupled to the electrostatic discharge protector.
15. A system including:
a liquid crystal display; and
a chipset coupled to the liquid crystal display, the chipset including:
a laser; and
an electrostatic discharge protector coupled to an anode of the laser, the electrostatic discharge protector capable of shunting excess current resulting from an electrostatic discharge away from the anode of the laser.
16. The system of claim 15, wherein a modulation signal is coupled to the anode of the laser through the electrostatic discharge protector.
17. The system of claim 15, wherein the electrostatic discharge protector is an integrated circuit.
18. The system of claim 15, wherein the anode of the laser is wire bonded to an output of the electrostatic discharge protector.
19. The system of claim 15, wherein the laser is a Vertical Cavity Surface Emitting Laser.
