Silicon Photonics for High-Capacity Optical Interconnects
* Hon Ki Tsang, The Chinese University of Hong Kong, Hong Kong David Chan, The Chinese University of Hong Kong Dan Yi, The Chinese University of Hong Kong Xuetong Zhou, The Chinese University of Hong Kong We review recent progress in silicon photonics for high-speed multi-lane data transceivers. We describe silicon photonic modulators for wide free spectral range WDM transmission, high extinction PAM-8 modulation, and IQ data modulation and present advanced waveguide grating couplers suitable for large-volume manufacturing with under 1dB insertion loss to standard single mode fibers. We also review progress towards the implementation of photonic signal processors for polarization division multiplexing and mode-division multiplexing in optical fiber interconnects. |

By using those QD-CCLs and -SOAs, we have experimentally demonstrated bi-directional millimeter-wave-over-fiber wireless fronthaul transmission links and optical super-channel coherent systems, which have clearly indicated that both QD-CCLs and -SOAs are critical building blocks of achieving broadband and high speed converged optical and wireless access network systems. |

Addressing the challenges of future telecommunication networks with advanced photonic integration technologies
* David Bitauld, III-V Lab / Nokia Bell Labs, France We will discuss the evolving needs of different segments of telecommunication networks and how to address them with advanced photonic integration technologies ranging from complex epitaxial regrowth to hybrid and heterogeneous integration. Indeed, while high performances are desirable across the whole network, cost and energy consumption constrain the technology that can be deployed. With that in mind different research path are explored to reach the targets set by future telecommunication standards. |

Passively Assembled, Broadband Evanescent Couplers for Sustainable Pb/s Co-Packaged Optics
* Drew Weninger, Massachusetts Institute of Technology, United States of America Luigi Ranno, Massachusetts Institute of Technology, United States of America Samuel Serna, Bridgewater State University, United States of America Lionel Kimerling, Massachusetts Institute of Technology, United States of America Anuradha Agarwal, Massachusetts Institute of Technology, United States of America A passively assembled chip-to-interposer evanescent coupler between silicon nitride and silicon was experimentally demonstrated between 1480-1640 nm with an average coupling loss upper limit of -2.16 dB (minimum of -0.93 dB) and an average 1 dB alignment tolerance of 1.14 um. Results show the viability of this coupler to help achieve Pb/s co-packaged optics switch performance by eliminating active fiber-to-chip alignment and scaling down optical input/output pitch at the die level. |

InAs/InP Quantum Dash Semiconductor Optical Amplifiers for Modern Communication Networks
* Youxin (Linda) Mao, National Research Council Canada , Canada We demonstrate on a series of C-Band and L-band quantum dash (QD) semiconductor optical amplifiers (SOAs) with different numbers of QD stacked layers. The overall preformation was investigated. The small-signal gain and noise figure were obtained at about 26.4 dB and 6.3 dB, respectively, at 1550 nm. Less gain competitions were observed from our QD-SOAs comparing to EDFA. The QD-SOAs were verified in a millimeter-wave (mmW) radio-over-fiber (RoF) fronthaul wireless link with 24-Gb/s (64QAM 4GBaud). |
