This paper aims to present the design and the achieved results on a CMOS electronic and photonic integrated device for low cost, low power, transparent, mass-manufacturable optical switching. An unprecedented number of integrated photonic components (more than 1000), each individually electronically controlled, allows for the realization of a transponder aggregator device which interconnects up to eight transponders to a four direction colorless-directionless-contentionless ROADM. Each direction supports 12 200-GHz spaced wavelengths, which can be independently added or dropped from the network. An electronic ASIC, 3-D integrated on top of the photonic chip, controls the switch fabrics to allow a complete and microsecond fast reconfigurability

Abstract-We review recent work done by the photonics packaging platform ePIXpack that serves the academic community with packaging & assembly developments in the area of integrated photonics. The paper includes recent examples of our packaging and assembly work, covering a broad range of technologies from silicon photonics to InP based devices. Index Terms-Hybrid integrated circuit packaging, Photonic integration, Silicon-on-insulator (SOI) I. INTRODUCTIONThe need for next generation carrier networks with capacities of 100Gbit/s transmission rate and beyond is driven by ubiquitous internet access, video driven IP traffic, highdefinition TV broadcast etc. [1,2]. Networks will need to handle constantly increasing bandwidth, while the underlying fiber infrastructure naturally only undergoes slow changes. This requires advanced solutions for high transmission capacity, which eventually can only be provided by integrated photonics devices. One option is silicon photonics. Siliconon-Insulator (SOI) is becoming an attractive passive optical integration platform due to its flexibility in terms of optical design. Thin SOI (~200nm) yields high-index contrast nanowaveguides [3] However, there still remain many challenges for silicon photonics to become an accepted technology in optical communications, e.g. integration of the source, efficient modulation, and polarization dependence.

A 4OAMx4WDM switching experiment has been carried out combining an innovative integrated tunable OAM multiplexer based on 4-concentric omega-shaped silicon waveguides and a refractive element-based OAM demultiplexer; operation is demonstrated up to 120Gb/s.
