6-GHz all-pass-filter-based delay-and-sum beamformer in 130nm CMOS
A broadband RF delay-and-sum (DAS) beamformer, which employs wide-band CMOS all-pass filters for achieving the desired time delays, is discussed in this work. The use of all-pass filters eliminatesExpand

Geometrical effects in the loading of an optical atom trap (6 pages)
Loading of atoms contained in a magneto-optic trap into an optical trap formed with the focused laser beam from a $\mathrm{C}{\mathrm{O}}_{2}$ laser is examined. We show that while the loadingExpand

10-GHz current-mode 1st- and 2nd-order allpass filters on 130nm CMOS
Novel CMOS wide-bandwidth 1st- and 2nd-order current-mode allpass filters are proposed in this paper. The 1st-order filter consists of only one transistor, two resistors and one grounded inductor. AnExpand

Low-spatial-coherence high-radiance broadband fiber source for speckle free imaging.
We design and demonstrate a fiber-based amplified spontaneous emission (ASE) source with low spatial coherence, low temporal coherence, and high power per mode. ASE is produced by optically pumping aExpand
