Toward the application of 400 G optical receiver chips in communication systems, this paper presents a 1×4 photodetector (PD) array with monolithic integrated InP microlenses structure. The absorption layer PD question includes non-depleted, partially depleted, and depleted regions. This third-order composite absorber accelerates diffusion electrons balances transport times holes electrons. Therefore, high-speed high responsivity characteristics device can be realized. integration on...
Compound refractive lenses (CRL) are broadly used at X-ray free-electron laser (XFEL) facilities for they less sensitive to angular vibrations. XFEL spectroscopy endstations need long-range tunable photon energy and separately controlled beam size in the vertical horizontal direction. However, focal distance of CRL is photon-energy dependent while sample positions fixed. Transfocators thus proposed which grouped can be inserted removed from beamline, allowing fast switch between different...
Brilliant synchrotron radiation and x-ray free-electron laser facilities have promoted the development of spectroscopy, especially resonant inelastic scattering femtosecond time-resolved spectroscopy. Comparing with flat crystals, spherically bent crystals (SBCs) are widely used in relevant spectrometers for focusing, which will dramatically improve detection efficiency. Therefore, focal properties SBCs should be experimentally well-investigated. Here, we build a device based on Rowland...
