1.5 μm 8 × 12.5 Gb/s of hybrid integrated TOSA with isolators and ROSA for 100 G

Compact transmitter and receiver optical sub-assemblies (TOSA and ROSA) are fabricated in our laboratory and have an aggregated capacity of 100 Gb/s. Specially, directly modulated laser (DML) drivers with two layers of electrical circuit boards are designed to inject RF signals and bias currents sep
