Based on the optical antenna composed of etched trenches on a waveguide, we propose two integrated waveguide-based optical tweezers for the first time for trapping micro- and nano-particles. A quasi-Gaussian beam and a quasi-spherical-wave field well above the antenna are produced and the optical trapping of the microparticle and nanoparticle is demonstrated. The corresponding upward beams generate gradient forces up to hundreds of pN/W, which is enough to trap particles in microscale and nanoscale effectively. Particles well above the antennas, as high as about 18 μm, can be trapped. This new type of optical tweezers based on photonic antennas is believed to pave the way to build fully integrated photonic circuits with large-scale parallel particle manipulation.","PeriodicalId":178563,"journal":{"name":"Optoelectronic Devices and Integration X","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114346441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the scenario of coherent optical transmission and interconnect, a highly beneficial but rarely explored target is to re-generate a Kerr soliton microcomb at the receiver side as local oscillators that conserve the frequency and phase property of the incoming data carriers, so that to enable coherent detection with minimized optical and electrical compensations. Also, in the scenarios of all-optical signal regeneration, a multi-wavelength coherent laser array is also needed to provide the coherent pump fields that enable phase-sensitive parametric amplification of the degraded data signals and constitute regenerative phase transfer functions. In this talk, we will introduce our recent experiments that implement re-generation of a Kerr soliton microcomb that faithfully clones the frequency and phase coherence of another microcomb. We show that such coherence-cloned carrier and LO microcombs can greatly facilitate coherent data receiving by making DSP-based compensations for carrier-LO frequency offsets and phase drifts substantially easier, and at most 1000 times more energy-saving, comparing with a system adopting individual laser carriers and LOs. Moreover, we will also discuss that the coherence-cloned Kerr microcombs can be used to implement multi-channel, configurable all-optical signal regeneration in nonlinear silicon waveguide, phase regenerations of twochannel BPSK signals are demonstrated with prominent signal quality improvements. Our work reveals that, in addition to providing a multitude of laser tones, regulating the frequency and phase of Kerr soliton microcombs among data transmitters, regenerators, receivers within an optical network can significantly improve the network performance in terms of signal quality, power consumption, and simplicity.","PeriodicalId":178563,"journal":{"name":"Optoelectronic Devices and Integration X","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116216329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sagnac loop structure is a significant interference structure in optic fiber sensors for strain measurement. In this research, we propose a sensor structure that links a commercial Panda PMF to a 4° TFBG. With an analysis of the sensitization effect of TFBG to the interference sensors, there will be a significant enhancement of sensitivity. Based on the analysis, we demonstrate a sensor that combined TFBG with PMF to enhance the sensitivity. When a strain affects the sensor, the spectra will shift towards a longer wavelength direction. When a strain affects the sensor, the spectra will shift towards a longer wavelength direction. The proposed sensor can provide a sensitivity up to 51.9pm/ and 50.5pm/.
