| 1 | A collinear tandem time-of-flight mass spectrometer for infrared photodissociation spectroscopy of mass-selected ions显示文摘An apparatus based on collinear tandem time-of-flight mass spectrometer has been designed for the measurement of infrared photodissociation spectroscopy of mass-selected ions in the gas phase.The ions from a pulsed laser vaporization supersonic ion source are skimmed and mass separated by a Wiley-McLaren time-of-flight mass spectrometer.The ion of interest is mass selected,decelerated and dissociated by a tunable IR laser.The fragment and parent ions are reaccelerated and mass analyzed by the second time-of-flight mass spectrometer.A simple new assembly integrated with mass gate,deceleration and reacceleration ion optics was designed,which allows us to measure the infrared spectra of mass selected ions with high sensitivity and easy timing synchronization. | WANG GuanJun CHI ChaoXian XING XiaoPeng DING ChuanFan ZHOU MingFei | 2014 | Science China Chemistry2014，57，1： | 2 |

| 3 | Silicon nonlinear switch as a conditional circulator for monostatic LiDAR systems显示文摘All-optical silicon-photonics-based LiDAR systems allow for desirable features in scanning resolution and speed,as well as leverage other advantages such as size, weight, and cost. Implementing optical circulators in silicon photonics enables bidirectional use of the light path for both transmitters and receivers, which simplifies the system configuration and thereby promises low system cost. In this work, to the best of our knowledge, we present the first experimental verification of all-passive silicon photonics conditional circulators for monostatic LiDAR systems using a nonlinear switch. The proposed silicon nonlinear interferometer is realized by controlling signal power distribution with power-splitting circuits, allowing the LiDAR transmitter and receiver to share the same optical path. Unlike the traditional concept requiring a permanent magnet, the present device is implemented by using common silicon photonic waveguides and a standard foundry-compatible fabrication process. With several additional phase shifters, the demonstrated device exhibits considerable flexibility using a single chip, which can be more attractive for integration with photodetector arrays in LiDAR systems. | Mingfei Ding Yiwei Xie Hao Yan Abu Naim R.Ahmed Reza Safian Swapnajit Chakravarty Leimeng Zhuang Pengcheng Jiao Huan Li Liu Liu Daoxin Dai | 2022 | Photonics Research2022，10，2： | 0 |
