ABSTRACT:
An optoelectronic device comprising a gradient index lens having an optical length, L, wherein L=P/4+NP/2, where N is an integer equal to or greater than 0 and P is the pitch of the gradient index lens. If the desired focus spot is spaced from the end face of the gradient index lens, the optical length L can be adjusted accordingly as a function of that distance and the index of refraction of the medium occupying that distance.
