We have designed and fabricated a directed logic architecture consisting of two silicon microring resonators that can perform XOR XNOR operations. The are modulated through thermo-optic effect. Two electrical modulating signals applied to the represent operands logical operation. function is evaluated propagation light in device, result represented by output optical signal. Both operations at 20 kbits demonstrated.
We experimentally demonstrate a spatially non-blocking five-port optical router, which is based on microring resonators tuned through the thermo-optic effect. The characteristics of microring-resonator-based switching element are investigated to achieve balanced performances in its two output ports. router fabricated SOI platform using standard CMOS processing. effective footprint device about 440×660 μm2. have 3-dB bandwidths larger than 0.31 nm (38 GHz), and extinction ratios better 21 dB...
The optical switches for single-mode operation cannot be directly utilized in communication and interconnect systems adopting mode-division multiplexing. In this paper, three general architectures on-chip space mode switching are proposed, which optimized switching, plus local global respectively. A silicon thermo-optic 2×2 four-mode switch is demonstrated. minimum maximum link insertion losses 16.0 20.9 dB (including ∼6 dB coupling loss), respectively, the wavelength range of 1525–1565 nm,...
We propose and demonstrate a directed OR/NOR AND/NAND logic circuit consisting of two parallel microring resonators (MRRs). use electrical signals representing the operands logical operation to modulate MRRs through thermo-optic effect, respectively. The final results are represented by output optical signals. Both operations at 10 kbps demonstrated.
Data exchange among different mode channels is indispensable for optical communication system adopting mode-division multiplexing. Traditional device complex in procedure and large footprint, which makes it not suitable dense large-scale photonic integration. Utilizing the degree of freedom silicon meta-structure, we design an ultracompact optically broadband between TE0 TE1 modes by step-by-step inverse-design method considering axisymmetric constraint. Simulation result shows that robust...
In this paper, we review the status of multifunctional experimental platform at National Laboratory High Power Laser and Physics (NLHPLP). The platform, including SG-II laser facility, 9th beam, upgrade (SG-II UP) 5 PW is operational available for interested scientists studying inertial confinement fusion (ICF) a broad range high-energy-density physics. These facilities can provide important capabilities by combining different pulse widths nanosecond, picosecond, femtosecond scales....
This study, via combined analysis of geophysical and geochemical data, reveals a lithospheric architecture characterized by crust-mantle decoupling vertical heat-flow conduits that control orogenic gold mineralization in the Ailaoshan belt on southeastern margin Tibet. The mantle seismic tomography indicates decoupled deformation, defined from previous anisotropy analysis, was formed upwelling lateral flow asthenosphere, driven deep subduction Indian continent. Our magnetotelluric images...
