ABSTRACT:
A device includes a VCSEL, an optical fiber, and a lens. The VCSEL generates optical light signals having a spatial emission pattern based around an axis of emission. Light signals emitted from the VCSEL substantially along or near the axis of emission are known as high speed modulation patterns. Light signals emitted at angles away from the axis of emission are known as slow speed modulation patterns. Slow speed modulation patterns become slower as the angle between the emitted light signals and the axis of emission increase. The lens is selectively positioned between the VCSEL and the optical fiber for focusing the high speed modulation patterns of the light signals on the optical fiber, and the lens substantially does not focus the slow speed modulation patterns of the light signals on the optical fiber.
