Abstract
A 1.3μm laser mounted in a low-cost compact disc package has been coupled to single-mode fibre using two graded-index lenses. Here we present results of calculations showing how to pick lens pitches for given coupling efficiency/sensitivity trade-offs. In addition, we note that the effective angular alignment can be quite sensitive, and propose a means of avoiding this difficulty.
