Fiber-chip-coupling modules with up to 50 GHz modulation bandwidth and reusable fiber-chip-coupling mechanism

We designed and fabricated DIL-modules with a reusable optical coupling set-up, which is well suited for small-scale production and rapid prototyping of waveguide-fed InP and GaAs OEICs like diode lasers, semiconductor amplifiers and optical modulators. The light output of these OEICs is collected with high efficiency into tapered single mode fibers with a patented set-up. The modules are temperature controlled within an ambient range from 15 degrees C to 40 degrees C and electrical modulation signals up to 50 GHz can be fed via RF connectors to the OEIC.
