Integrated two-state AWG-based multiwavelength laser

“…An antireflection coating was applied to the cleaved facet, and an array of lensed fiber tips [12] permitted simultaneous access to the inputs and outputs. The coupling loss between the fiber tips and device waveguides was estimated to be in the order of 6 dB [12]. The device was mounted on a Peltier cooled copper chuck.…”

Microengineered Two-Dimensional Arrays of Monomode Optical Fibers

“…Reported positioning accuracy with these passive-alignment schemes is around 0.5-5 µm, which either does not meet the requirements for single-mode fiber transmission or is very expensive [9]. Active-alignment methods include electrothermal actuators [10], laser welding [11], electrostatic actuators [12], [13], piezo-actuators [14], rotational alignment [15], and manual alignment [16]. These methods can either be applied to singlefiber 1-D arrays of fibers only or are tremendously expensive in terms of manpower.…”

Manufacture of Two-Dimensional Monomode Optical Fiber Array Using MEMS Technology

“…Using r2 w, (A(XZ, y_ )) -w, (B(XZ, yz)) 2 9 (18) the geometrical system, as shown in Figure 9, is derived.…”

“…These fibres are however more expensive, thereby greatly increasing the overall system costs. Several active alignment methods, in which the fibres are moved by different means, to minimize the coupling losses have been reported [8,9], but they are either sequential alignment processes, and therefore very expensive, or cannot physically be scaled up to produce two-dimensional fibre arrays.…”
