Abstract
We report a newly developed 45-Gbuad, 32-pixel two-dimensional photodetector array (2D-PDA) and the photodetector's performance in free space optical (FSO) communication. With the selected 4 × 4 pixels in 32 pixels to preserve large active area, the direct coupling between high data rate FSO beam and the 2D-PDA was demonstrated to improve optical alignment tolerances. The eye diagram, bit error rate (BER), and photo-current characteristics in the range 10-45 Gbaud were evaluated for 4 × 4 pixels in plane.
