The novelty of the photonic chip lies on the fact that it eliminates the need for fiber pigtails and external polarization control and enables ultra-compact implementations by virtue of the hybrid integration of the laser source and the photodetectors on-chip. We present the MRR-based sensing mechanism, and we explain the associated power budget limitations that are particularly present in a fully integrated and arrayed version of this type of sensor. We then present in detail the simulations for the design of the grating coupler that couples the light from the flip-chip bonded laser source into the TriPleX platform and the multi-mode interference (MMI) coupler that splits the optical power among the eight parallel MRRs. We show that we can achieve a grating coupler with coupling efficiency close to 30% and an MMI coupler with insertion loss and power imbalance below 0.5 dB. We finally explain why this performance is sufficient in terms of available power budget on-chip for the proper operation of the novel ultra-compact biosensor.

We achieve 100-Gb/s transmission over 1625-m, and demonstrate the flexibility of the transmitter inside data-center networks. 1. Introduction Next generation 100 Gigabit Ethernet (GbE) interfaces have the potential to overcome the limitations in terms of throughput and line card density that 10 and 40 GbE interfaces face today in intra-data center networks (iDCNs). For this reason they are expected to be widely deployed in the future, interconnecting switches at the higher layers of the electrical packet switching hierarchy or switches at the edge of the optical circuit switched (OCS) domain of these networks over distances up to 2-km [1]. Along this line, we recently demonstrated transmitters for single-and multi-100 GbE interfaces, which rely on the hybrid integration of an electro-optic (EO) polymer photonic circuit (polyboard) with a laser diode and u...

Full-duplex 10G/2×10G transmission with reflective ONUs is validated for 20dB budget and 25km reach. An optional 10Gb/s FDM/TDM mode is verified.
