Patent ID: 6925099

Claim:
An optoelectronic device consisting of: only one vertical cavity surface emitting laser for generating optical light signals having a spatial emission pattern based around an axis of emission, light signals emitted from the only one vertical cavity surface emitting laser substantially along or near the axis of emission are known as high speed modulation patterns, and light signals emitted at angles away from the axis of emission are known as slow speed modulation patterns, and wherein the slow speed modulation patterns of the light signals become slower as the angle between the emitted light signals and the axis of emission is increased, and wherein the only one vertical cavity surface emitting laser operates at speeds above two and one-half Gigabits per second; only one element having only one aperture, the only one aperture sized so as to allow the high speed modulation patterns of the light signals to pass therethrough, and the only one aperture sized so as to substantially prevent the slow speed modulation patterns of the light signals from passing therethrough; only one optical fiber; and only one lens positioned between the only one vertical cavity surface emitting laser and the only one optical fiber, the only one lens positioned in the only one aperture of the only one element, and wherein the only one lens focuses the high speed modulation patterns of the light signals on the only one optical fiber, and wherein the only one lens, when viewed from a perspective substantially perpendicular to the axis of emission of the only one vertical cavity surface emitting laser, has a shape of an ellipse, and wherein the only one lens is separated from the only one optical fiber by a gap, and wherein the only one element is separated from the only one optical fiber by the gap, and wherein the only one element is positioned between the only one vertical cavity surface emitting laser and the only one optical fiber, and wherein the only one optical fiber includes a core surrounded by cladding, and wherein the high speed modulation patterns of the light signals are focused on the core.
