Terahertz (THz) radar has been considered as a new solution to the dilemmas in performing ultra-high-resolution imaging and obtaining highly precise target information. In this work, a photonic THz…
Orbital angular momentum (OAM) modes have becoming more promising to further achieve higher spectral efficiency and data capacity in space-division-multiplexing (SDM) fiber communication systems. I…
Orbital angular momentum (OAM) beams, featuring with unique spatial field distributions, have been extensively investigated and applied into a wide range of fields. In most applications, OAM beams …
Orbital angular momentum (OAM) modes, featured by the unique properties of the helical phase front and annular intensity profile, have shown enormous potential for a wide range of applications. Opt…
A switchable dual-band binary and single-band quaternary phase-coded microwave signal generator based on a single dual-polarization dual-drive Mach–Zehnder modulator (DP-DDMZM) is proposed. Two r…
In this paper, we propose and experimentally demonstrate a photonic terahertz (THz) continuous-wave vector imaging scheme using an optical frequency comb (OFC), to overcome the influence of phase n…
A two-dimensional grating coupler (2D GC) with four access waveguides is proposed and demonstrated for polarization independent and perfectly vertical coupling. Benefitting from the perfectly verti…
We propose and experimentally demonstrate a vertical fibre interfacing interleaved angled MMI (AMMI) for wavelength division (de)multiplexing (WDM) near 1550 nm. This 6-channel WDM device is compo…
Photonics-aided terahertz (THz) wireless systems have been progressively developed to accommodate the forthcoming wireless communication with extremely high data rates in recent years. However, res…
Mode-division multiplexing (MDM) is a new method of space-division multiplexing (SDM) that can break through the limitation of single-mode transmission capacity and greatly improve the capacity of …
