Single-mode-fiber direct coupled 10-Gbps VCSEL-TOSA on flexible substrate platform

A new-type 10-Gbps VCSEL-TOSA (vertical cavity surface emitting laser transmitter optical sub-assembly) was demonstrated with single-mode-fiber direct coupling optics and a flexible substrate platform. The TOSA showed high fiber coupling efficiency (-1.6 dB) and clear 10-Gbps eye-opening with -2.6 dBm average optical power and 6 dB extinction ratio.
