“…The electric crosstalk in WLAs has been investigated. [63][64][65][66] The solutions include reducing the intra-chip crosstalk and minimizing the crosstalk occurring between WLAs and electrical peripherals. The former can be achieved by electric isolation with deep trenches and=or proton implantation between lasers as well as the use of larger device separation.…”

Wavelength division multiplexing (WDM) laser arrays (WLAs) can provide compact light sources for optical telecommunications, interconnections, switching, and optical sensing applications. The technologies to realize WLAs are reviewed and discussed with focus on wavelength registration and manufacturing complexity. WLAs can be realized in monolithic or hybrid integration approaches. The issues and challenges for applying monolithic or hybrid integration to realize WLAs will be discussed. The laser arrays based on hybrid laser structure and the silicon photonics foundry fabrication model will be highlighted.

“…1 depicts the final package which results. The laser bar is a 32-wide array of 1300-nm, InP ridge lasers on 375-km centers [3], [4]. For clarity, only 5 of the 32 lasers are shown in the drawings.…”

“…On top of the master stages, beneath the laser-holding plate (at left), are motorized, precision (x, y, 0, 4) stages. Likewise, beneath the fiber-holding plate (at right) are motorized, precision ( z , 4) stages. The resolution of the precision translation stages is 0.1 pm; the resolution of the angular stages is 0.00 1 O. Motorized + adjustment is unnecessary because laser-to-fiber alignment is not very sensitive in that direction; it suffices to perform onetime tilt adjustments via the various leveling screws shown.…”

This paper describes techniques and machinery for first-level packaging of laser-to-fiber interconnects using batch assembly and active alignment. These techniques are economical because the costs of labor-intensive processes, such as parts handling, fiber-polishing, and alignment, are shared among the many elements of the array. Using these techniques, prototype packages have been built consisting of 32-wide arrays of 1300nm lasers coupled to 32-wide arrays of single-mode fiber-optic stubs. Building the package involves three steps: 1) preparing the laser array for handling and alignment by soldering it to a metallized silicon carrier; 2) building the fiber array by stripping the fibers, placing them precisely into etched silicon V-grooves, bonding them in place, and polishing both ends; and 3) aligning the two arrays to each other using batch, active alignment. Batch alignment succeeds to the extent that each array is collinear, so the collinearity achieved in processes 1) and 2) is crucial. Typically, collinearity of f l pm or better is achieved for each array. When such arrays are batch aligned using the techniques described herein, the average coupling efficiency is about 88% as large as it would be if each laser-fiber pair were optimally aligned individually.
