DOI: 10.1002/mrm.29260
Abstract: Homodyne filtering is a standard preprocessing step in the estimation of SWI. Unfortunately, SWI is not quantitative, and QSM cannot be accurately estimated from filtered phase images. Compared with gradient‐echo sequences suitable for computing QSM,… read more here.

The EML as Analogue Radio-Over-Fiber Transceiver—A Coherent Homodyne Approach

DOI: 10.1109/jlt.2018.2870537
Abstract: Analogue radio-over-fiber schemes avoid transmission overhead as they dismiss digitization and processing of radio signals at head- and tail-end of the mobile optical fronthaul. Typically laid out following an intensity-modulation/direct-detection methodology, such systems do not… read more here.

DOI: 10.1117/1.oe.57.8.086111
Abstract: Abstract. We demonstrate influences of the power splitting ratio of the quadrature-arm to the input signal on both receiver sensitivity and residual phase error for a 10-Gb/s binary phase-shift keying coherent receiver based on an… read more here.

DOI: 10.1364/oe.465186
Abstract: We present a novel method to fully estimate Gaussian bipartite polarization states using only a single homodyne detector. Our approach is based on [Phys. Rev. Lett.102, 020502 (2009)10.1103/PhysRevLett.102.020502], but circumvents additional optics, and thereby losses,… read more here.
