    Underwater wireless optical NOMA communication experiment system exploiting GaN-based micro-LED array grouping

    梁彦军殷洪玺黄安季秀阳...
    1-6页
    查看更多>>摘要：This paper has proposed an experimental system for non-orthogonal multiple access[NOMA]wireless optical communi-cation in challenging underwater turbulent environments,employing the gallium nitride[GaN]-based micro-LED array.This design of the GaN-based micro-LED array enables the independent transmission of signals from distinct data streams within the NOMA framework,facilitating direct optical power-domain superposition of NOMA signals.The experimental setup involves emulating oceanic turbulence channels,characterized by varying the level of scintillation intensity,to thor-oughly investigate the bit error rate[BER]performance.The outcomes unequivocally demonstrate the superiority of our proposed NOMA scheme,as compared to conventional circuit-driven optical NOMA systems utilizing fixed LED array group-ing,particularly in the presence of turbulent underwater channels.The proposed NOMA scheme exhibits consistently supe-rior BER performance and maintains excellent linearity at the lower frequencies while effectively mitigating signal distortion at the higher frequencies.

    Simple real-time high-sensitivity heterodyne coherent optical transceiver at intraplane satellite communication

    曲元哲张倩武王演祎陈彦昊...
    7-13页
    查看更多>>摘要：In this paper,we demonstrate a high-sensitivity and real-time heterodyne coherent optical transceiver for intraplane sat-ellite communication,without digital-to-analog converter[DAC]devices and an optical phase lock loop[OPLL].Based on the scheme,a real-time sensitivity of-49 dBm is achieved at 5 Gbps QPSK.Because DAC is not needed at the transmitter,as well as OPLL at the receiver,this reduces the system cost.Furthermore,the least required Rx ADC bit-width is also discussed.Through theoretical analysis and experimental results,our cost-effective transceiver satisfies the scenario and could be a promising component for future application.

    LP modes exchange based on multiplane light conversion

    钟亚楠林楚璇方浚丞雷霆...
    14-18页
    查看更多>>摘要：Data exchange between different mode channels is essential in the optical communication network with mode-division multiplexing[MDM].However,there are challenges in realizing mode exchange with low insert loss,low mode crosstalk,and high integration.Here,we designed and fabricated a mode exchange device based on multiplane light conversion[MPLC],which supports the transmission of LP01,LP11a,LP11b,and LP21 modes in the C-band and L-band.The simulated exchanged mode purities are greater than 85％.The phase masks were fabricated on a silicon substrate to facilitate the integration with optical systems,with an insert loss of less than 2.2 dB and mode crosstalk below-21 dB due primarily to machining inaccuracies and alignment errors.We carried out an optical communication experiment with 10 Gbit/s OOK and QPSK data transmission at the wavelength of 1550 nm and obtained excellent performance with the device.It paves the way for flexible data exchange as a building block in MDM optical communication networks.

    Enhancing the ability of single-pixel imaging against the source's energy fluctuation by complementary detection

    蔡俊杰龚文林
    19-24页
    查看更多>>摘要：The source's energy fluctuation has a great effect on the quality of single-pixel imaging[SPI].When the method of com-plementary detection is introduced into an SPI camera system and the echo signal is corrected with the summation of the light intensities recorded by two complementary detectors,we demonstrate,by both experiments and simulations,that complementary single-pixel imaging[CSPI]is robust to the source's energy fluctuation.The superiority of the CSPI struc-ture is also discussed in comparison with previous SPI via signal monitoring.

    Geometric phase helical PSF for simultaneous orientation and 3D localization microscopy

    周勇壮张洪硕沈咏Andrew R.Harvey...
    25-30页
    查看更多>>摘要：The 3D location and dipole orientation of light emitters provide essential information in many biological,chemical,and physical systems.Simultaneous acquisition of both information types typically requires pupil engineering for 3D localization and dual-channel polarization splitting for orientation deduction.Here we report a geometric phase helical point spread function for simultaneously estimating the 3D position and dipole orientation of point emitters.It has a compact and simpler optical configuration compared to polarization-splitting techniques and yields achromatic phase modulation in contrast to pupil engineering based on dynamic phase,showing great potential for single-molecule orientation and localization microscopy.

    Measurable speckle gradation Hadamard single-pixel imaging

    周立宇白艳锋付芹朱孝辉...
    31-35页
    查看更多>>摘要：The array spatial light field is an effective means for improving imaging speed in single-pixel imaging.However,distinguish-ing the intensity values of each sub-light field in the array spatial light field requires the help of the array detector or the time-consuming deep-learning algorithm.Aiming at this problem,we propose measurable speckle gradation Hadamard single-pixel imaging[MSG-HSI],which makes most of the refresh mechanism of the device generate the Hadamard speckle patterns and the high sampling rate of the bucket detector and is capable of measuring the light intensity fluctuation of the array spatial light field only by a simple bucket detector.The numerical and experimental results indicate that data acquis-ition in MSG-HSI is 4 times faster than in traditional Hadamard single-pixel imaging.Moreover,imaging quality in MSG-HSI can be further improved by image stitching technology.Our approach may open a new perspective for single-pixel imaging to improve imaging speed.

    Ultra-compact and broadband polarization-insensitive mode-order converting power splitter

    陈浩琪姚润葵汪鹏君符强...
    36-41页
    查看更多>>摘要：A polarization-insensitive mode-order converting power splitter using a pixelated region is presented and investigated in this paper.As TEo and TMo modes are injected into the input port,they are converted into TE1 and TM1 modes,which evenly come out from the two output ports.The finite-difference time-domain method and direct-binary-search optimization algo-rithm are utilized to optimize structural parameters of the pixelated region to attain small insertion loss,low crosstalk,wide bandwidth,excellent power uniformity,polarization-insensitive property,and compact size.Experimental results reveal that the insertion loss,crosstalk,and power uniformity of the fabricated device at 1550 nm are 0.57,-19.67,and 0.094 dB in the case of TE polarization,while in the TM polarization,the relevant insertion loss,crosstalk,and power uniformity are 0.57,-19.40,and 0.11 dB.Within a wavelength range from 1520 to 1600 nm,for the fabricated device working at TE polarization,the insertion loss,crosstalk,and power uniformity are lower than 1.39,-17.64,and 0.14 dB.In the case of TM polarization,we achieved an insertion loss,crosstalk,and power uniformity less than 1.23,-17.62,and 0.14 dB.

    Ultralow cross talk arrayed waveguide grating integrated with tunable microring filter array

    胡鹤鸣刘世平李天文范永杰...
    50-54页
    查看更多>>摘要：The silicon-based arrayed waveguide grating[AWG]is widely used due to its compact footprint and its compatibility with the mature CMOS process.However,except for AWGs with ridged waveguides of a few micrometers of cross section,any small process error will cause a large phase deviation in other AWGs,resulting in an increasing cross talk.In this paper,an ultralow cross talk AWG via a tunable microring resonator[MRR]filter is demonstrated on the SOI platform.The measured insertion loss and minimum adjacent cross talk of the designed AWG are approximately 3.2 and-45.1 dB,respectively.Compared with conventional AWG,its cross talk is greatly reduced.

    55-59页
    查看更多>>摘要：We propose and demonstrate an integrated microwave photonic sideband selector based on the thin-film lithium niobate[TFLN]platform by integrating an electro-optic Mach-Zehnder modulator[MZM]and a thermo-optic tunable flat-top mi-croring filter.The sideband selector has two functions:electro-optic modulation of wideband RF signal and sideband selec-tion.The microwave photonic sideband selector supports processing RF signals up t0 40 GHz,with undesired sidebands effectively suppressed by more than 25 dB.The demonstrated device shows great potential for TFLN integrated technology in microwave photonic applications,such as mixing and frequency measurement.
