| 1 | Modular architecture for fully non-blocking silicon photonic switch fabric显示文摘Integrated photonics offers the possibility of compact,low energy,bandwidth-dense interconnects for large port count spatial optical switches,facilitating flexible and energy efficient data movement in future data communications systems.To achieve widespread adoption,intimate integration with electronics has to be possible,requiring switch design using standard microelectronic foundry processes and available devices.We report on the feasibility of a switch fabric comprised of ubiquitous silicon photonic building blocks,opening the possibility to combine technologies,and materials towards a new path for switch fabric design.Rather than focus on integrating all devices on a single silicon chip die to achieve large port count optical switching,this work shifts the focus towards innovative packaging and integration schemes.In this work,we demonstrate 1×8 and 8×1 microring-based silicon photonic switch building blocks with software control,providing the feasibility of a full 8×8 architecture composed of silicon photonic building blocks.The proposed switch is fully non-blocking,has path-independent insertion loss,low crosstalk,and is straightforward to control.We further analyze this architecture and compare it with other common switching architectures for varying underlying technologies and radices,showing that the proposed architecture favorably scales to very large port counts when considering both crosstalk and architectural footprint.Separating a switch fabric into functional building blocks via multiple photonic integrated circuits offers the advantage of piece-wise manufacturing,packaging,and assembly,potentially reducing the number of optical I/O and electrical contacts on a single die. | Dessislava Nikolova David M.Calhoun Yang Liu Sébastien Rumley Ari Novack Tom Baehr-Jones Michael Hochberg Keren Bergman | 2017 | Microsystems & Nanoengineering2017，3，1： | 3 |

| 4 | Ultralow-crosstalk,strictly non-blocking microring-based optical switch显示文摘We report on the first monolithically integrated microring-based optical switch in the switch-and-select architecture. The switch fabric delivers strictly non-blocking connectivity while completely canceling the first-order crosstalk. The 4 × 4 switching circuit consists of eight silicon microring-based spatial(de-)multiplexers interconnected by a Si/SiN dual-layer crossing-free central shuffle. Analysis of the on-state and off-state power transfer functions reveals the extinction ratios of individual ring resonators exceeding 25 dB, leading to switch crosstalk suppression of up to over 50 dB in the switch-and-select topology. Optical paths are assessed, showing losses as low as 0.1 dB per off-resonance ring and 0.5 dB per on-resonance ring. Photonic switching is actuated with integrated micro-heaters to give an ~24 GHz passband. The fully packaged device is flip-chip bonded onto a printed circuit board breakout board with a UV-curved fiber array. | QIXIANG CHENG LIANG YUAN DAI NATHAN C.ABRAMS YU-HAN HUNG PADRAIC E.MORRISSEY MADELEINE GLICK PETER O’BRIEN KEREN BERGMAN | 2019 | Photonics Research2019，7，2： | 1 |
