We report on a hybrid DWDM-TDM A optical access network that provides a route for integrating access and metro net- works into a single all-optical system.

We report upon a hybrid DWDM-TDMA optical access network that provides a road towards integrating access and metro networks into a single all-optical system.

We demonstrate a compact, fully tunable, narrowband 4th order pole-zero optical filter that is fabricated in a silicon complementary metal oxide semiconductor foundry.

A DWDM-TDMA PON using carrier distribution with symmetric 320Gb/s capacity is demonstrated over 124km field-installed fibers.

We propose and demonstrate a fault-tolerant WDM add-drop/branching unit for long-haul optical transmission systems.

We demonstrate a compact fully tunable narrowband fourth-order pole-zero optical filter that is fabricated in a silicon complementary-metal-oxide-semiconductor foundry.

A fully passive ring+tree PON architecture is demonstrated in a rural 80 km reach scenario and a urban 1:128 split configuration with field-deployed fibers, featuring RSOA-based ONUs with transmiss

We present the first experimental demonstration of a novel III-V-on-silicon distributed feedback laser type. All structures defining the laser cavity are defined in the silicon.

Together with the optimal basic design, buried heterostructure quantum cascade laser (BH-QCL) with semi-insulating regrowth offers a unique possibility to achieve an effective thermal dissipation a

A ring+tree PON is demonstrated from a 78 km reach rural to an urban 1:128 split configuration with field-deployed fibers at >31 dB budget and RSOA or SOA/REAM at the ONU.
