“…Standard silica telecommunications fibre has an outer diameter of 125 mm and a core diameter of 8 mm. Anisotropic etching has been used to form kinematic mounts for fibres [13], fibre cable connectors [14], and arrangements for connecting fibres to detectors and lasers [15,16]. These methods have been extended to incorporate planar lightwave circuits in complete opto-hybrid modules [17].…”

Optical microelectromechanical systems (MEMS) combine miniature optical components with precision fixtures, elastic suspensions, and microactuators, and allow complex functionality at low cost. However, the effect of the bounded nature of the beams propagating through the system on design is profound. The current paper reviews the fundamental consequences. Using a Gaussian beam formulation, models of guided modes in gradient index media, bounded beams and imaging components are constructed. Propagation algorithms are described. The alignment tolerances for common component trains such as fibre-to-fibre and beam-to-fibre connections are derived, limits on the curvature of reflecting surfaces are established, the scaling laws of free-space optical MEMS are presented and the effect of beam size on filter performance is clarified. Examples such as variable optical attenuators, optical cross-connect switches, filters and tunable lasers are discussed.

A positioning device for accurately positioning an array of multimode fibers with a cladding diameter of 125-140 mu m is described in this paper. The device has grooved sidewalls adapted to hold 16 fibers and includes a vacuum chamber communicating with openings in the beddings. It may be used to align a complete array of fibers in a single operation with respect to an array of elements such as lasers. A typical coupling-loss difference of 0.5 dB has been achieved for the alignment of an eight-element 140 mu m multimode fiber array with a laser array. This positioning device is part of the tooling, therefore is reusable. Experiments show that it is suitable and flexible for the alignment of multimode fibers in lasers, and is a cost-effective device.
