“…The active and passive alignment technologies [2], [3] are usually used for accurate alignment between pump lasers and the fibers or PMFs prior to packaging components. The active photonic alignment technology is the light to or from photonic components used to establish alignment prior to fixing components.…”

An oriented-dependence-microlens (ODM) visual alignment and packaging for lasers coupling to polarizationmaintaining-fibers (PMFs) is proposed and demonstrated. The ODM is fabricated by automatic grinding and accurate positioning techniques. The position accuracy of the grinding machine is ±1°, which is less than the aligned and fabricated angular tolerance of ±2°for the ODM necessary to achieve both high coupling of 80% and high polarized extinction ratio of 30 dB. This indicates that the ODM endface of the fast axis can be visually observed and then surface feature aligned to the axis of the laser polarization direction. A practical package of laser/PMF with compact size and a few components employing the ODM is also demonstrated. The proposed ODM with visually precise surface feature alignment to achieve both high coupling and polarization is beneficial for the application of laser/PMF modules for use in high-precision fiber optic gyroscopes and many high-performance and low-cost lightwave interconnections.

“…As a result, passive alignment techniques play an important role in low cost optoelectronic packaging. The general method to assemble the optical fiber is to position it in an etched V-groove and fK it with curing adhesive [2]. Unfortunately, it needs high accurate photolithography technique and the curing process will bring reliability problem.…”

The three-dimensional (3-D) shape of solder joint in fiber attachment soldering was predicted by employing Finite Element Method (FEM). Based on the minimum potential energy theorem and data from shape simulation, the influence of material and manufactuiing parameters on the Stand-Off Height (SOH) between optical fiber and substrate was analyzed in detail. The results showed that the z-axis alignment of optical fiber can be controlled by solder volume and solder joint design.
