DOI: 10.1007/s10043-017-0400-5

Abstract: A simple photonic microwave image-reject mixer (IRM) using two parallel phase modulators is proposed. First, a photonic microwave mixer with phase shift ability is achieved using two parallel phase modulators (PMs), an optical bandpass filter,… read more here.

DOI: 10.1109/jlt.2025.3581960

Abstract: A multiband microwave photonic filter (MPF) featuring wideband tunability, image interference suppression, and independent multi-channel tunability has been proposed and experimentally validated. The proposed MPF utilizes a photonic image-reject mixer (IRM) to effectively suppress image… read more here.

DOI: 10.1109/lmwc.2021.3086533

Abstract: A 7.8–9.8-GHz low-loss high- $T_{c}$ superconducting (HTS) image-reject Josephson junction mixer is presented in this letter. Image rejection is achieved using low-loss image rejection filters and a pair of parallel dual-mode resonators. Three cascaded Josephson… read more here.

DOI: 10.1364/ol.42.001105

Abstract: An all-optical and ultra-wideband microwave in-phase/quadrature (I/Q) mixer, based on a dual-parallel Mach-Zehnder modulator and a wavelength division multiplexer, is proposed. Due to the simultaneous frequency down-conversion and 360-deg tunable phase shifting in the optical… read more here.
