We have developed plastic-molded receptacle-lope vertical-cavity surface-emitting laser (VCSEL)-array modules directly push/pull connectable with the one-dimensional (1-D) conventional mechanically-transferable multifiber push-on (MPO) fiber connector and with a new two-dimensional (2-D) MPO-compatible fiber connector developed for this module. The VCSEL was mounted on the plastic-molded package using a highly precise completely alignment-free process using flip-chip solder bonding and ball-guide die bonding. These modules exhibit an optical coupling loss of 0.67 ± 0.23 dB (efficiency: 85.8 ± 2.93%) and a loss deviation of less than 0.26 dB for 100 matings with the fiber connector (MMF50). The modules were operated at a bit rate of 1 Gbps/ch without an isolator and showed floorless bit error rate (BER) performance at temperatures up to 70°C. At 1 Gbps/ch their optical sensitivity at a BER of 10-11 was -26.0 dBm ± 0.9 dB. These structures and techniques are applicable to high-density, high-throughput optical parallel interconnections and optical space-division switches.
