The random forest, a powerful machine learning algorithm, is introduced to improve the performance of silicon arrayed waveguide grating (AWG)-based fibre Bragg (FBG) wavelength interrogation. experimental results show proposed method has high interrogation accuracy with root mean squared error (RMSE) 0.73 pm in whole demodulation range.
A large-area binary blazed grating coupler for the arrayed waveguide grating (AWG) demodulation integrated microsystem on silicon-on-insulator (SOI) was designed for the first time. Through the coupler, light can be coupled into the SOI waveguide from the InP-based C-band LED for the AWG demodulation integrated microsystem to function. Both the length and width of the grating coupler are 360 μm...
We present a five-channel wavelength division multiplexed modulator module that heterogeneously integrates a 200 GHz channel-spacing silicon arrayed-waveguide grating multiplexer and a 20 Gbps electro-absorption modulator array, showing the potential for 100 Gbps transmission capacity on a 1.5x0.5 mm² footprint.
We summarize our research on LION switches exploiting wavelength routing in arrayed waveguide grating routers (AWGRs). We discuss the loopback-buffer, alloptical-NACK and all-optical-TOKEN architectures, presenting their effectiveness in terms of network performance and experimental studies. OCIS codes: (200.4650) Optical Interconnects; (200.6715) Switching.
In this Letter we demonstrate high-speed direct space-to-time pulse shaping with waveform reconfigurations down to the order of 1 ns. Our pulse shaper implementation incorporates a modified arrayed-waveguide grating structure and an array of optoelectronic reflection modulators.
IXO with its high throughput and spectral resolution will allow X-ray spectroscopy to become a standard working horse for astrophysics. The grating spectrometers on Chandra and XMM-Newton have opened the field, but due to their limited effective area only for the brightest sources and due to the way that gratings work only for point sources or very compact extended sources. With IXO, the effect...
Arrayed waveguide grating (AWG) is a promising technology for constructing high-speed large-capacity WDM switches, because it can switch fast, is scalable to large size and consumes little power. To take the full advantage of high-speed AWG, the routing control of a massive AWG-based switch should be as simple as possible. In this paper, we focus on the self-routing design of AWG-based switches...
The measured values of the wavelengths of 60 lines in the 1.1to 2.3-micron spectral region are reported. The absorption lines of the bands of methane and water vapor were used in the calibration. The methods of measurement are discussed. Also discussed are the methods of superimposing the well-known emission lines of several sources on the absorption lines that were measured. The values obtaine...
In the previous experiment diffraction and interference were discussed and at the end a diffraction grating was introduced. In this lab most of the things learned in the last experiment will be applied to measure the wavelengths of the lines in the visible spectrum of some elements. You will use a diffraction grating mounted on a spectrometer to measure the interference maxima for various wavel...
