“…One can design micro-lenses with surface profile to apply special requirements and/or to perform certain function. For example, the refractive type of micro-lens is well known to be used in coupling the light from a light emitter into an optical fiber [13][14]. In this approach, the advantage of micro-lens is emphasized on its focusing capability.…”

“…Starting with a certain system performance criterion, usage of an equal weight root mean square tolerance budget can help establish the individual tolerance criteria. 5 MODEL VALIDATION Validation of the model presented in this paper was done by comparing our evaluation of the apodized scaled or Strehi ratio with experimental coupling efficiency data taken from a paper [7]. We essentially predicted the experimental results presented in the paper and obtain good agreement.…”

This manuscript summarizes the work presented at the meeting. A more complete paper has already been submitted to a journal [1]. In effort to adapt the analysis of coupling lenses to the use of optical design software, we demonstrate that the coupling efficiency of a system can be related to an apodized and normalized point spread function.This approach allows the evaluation, optimization and tolerancing of systems which contain a fair amount of aberration. Comparison of theoretical predictions with experimental results shows good agreement. KEY WORDSLens coupling, design optimization, coupling efficiency. LENS DESIGN AND OVERLAP INTEGRALThe use of optical elements to affect laser-to-waveguide coupling is interesting since it provides beam magnification or mode matching. However, this raises the cost of the coupling system considerably; that is why it is important to be able to evaluate theoretical coupling performance. Since the numerical aperture of the beam emitted by a laser diode is usually in the range 0.4-0.6, the control of the coupling system's aberrations becomes critical. Our goal is to present a practical, engineering way to treat the problem that employs available lens design software and simple performance criteria such as the apodized point spread function and Strehl ratio.It is well established that the evaluation of the coupling efficiency (i) of a system is done using the overlap integral [2], 12
