In this paper, we present a monolithic vertical integration of a 850nm wavelength AlGaAs/GaAs-based vertical-cavity surface-emitting laser (VCSEL) and a 810nm wavelength AlGaAs/GaAs-based resonant cavity enhanced photodetector(RCE-PD). The receiving and transmitting of optical signals on two different wavelengths can be realized simultaneously by the single transceiving chip. Simulations show that,...
In this paper, an integrated optoelectronic chip, which can transmit optical signal at 849.2nm and receive optical signal at 803nm, is proposed. It is constructed by integrating a VCSEL unit above a PIN-PD unit. Analysis show that, the VCSEL unit has a threshold current around 1mA and a maximum output power around 1.2mW at 849.2nm, the PIN-PD unit has a highest absorption quantum efficiency above...
A vertically integrated device composed of Vertical-Cavity Surface-Emitting Laser (VCSEL) unit and Resonant Cavity Enhanced Photodiode (RCE-PD) unit is proposed, which has huge potential application perspectives for optical interconnects. The performance of the integrated device and the interaction of its two composing units are analyzed based on different structure optimization. As optimized, its...
We review our previously proposed topology reconstruction mechanism in the small world topology based optical data center network (DCN). We also present some recent experimental demonstration results, which verified that the topology reconstruction can reduce the number of hotspots and thus further accelerate data analysis jobs in DCN.
Optical Network-on-Chip (ONoC) is deemed as a promising candidate in future on-chip interconnection scenario. It is superior to the traditional electrical NoC in many aspects, such as the bandwidth density, power consumption and scalability. On-chip optical router is an indispensable building block in ONoC design. However, most reported optical routers are with four or five ports, which cannot be...
We design and experimentally fabricate a 8×8 arrayed waveguide grating router(AWGR) with a channel spacing of400 GHz based on silicon-on-insulator (SOI) platform. The arrayed waveguide region of this device is horseshoe-shaped to realize a small footprint of 730 μm × 580 μm. Experimental results show good cyclic performance. The crosstalk and insertion loss are about −21 dB and 2.7 dB, respectively...
We propose a silicon 2×2 optical switch which can simultaneous manipulate wavelength division multiplexing and mode division multiplexing signals. It is composed of broadband mode multiplexers, demultiplexers and single mode optical switch elements. For demonstration, we design and fabricate a prototype device using asymmetric directional coupler and Mach-Zehnder optical switch elements which can...
