Special Issue on the 70th Anniversary of Department of Electronic Engineering, Tsinghua University
This special issue is to celebrate the 70th Anniversary (24th April 2022) of Department of Electronic Engineering, Tsinghua University (DEETHU). It is aimed to highlight the most exciting research works recently carried out in DEETHU or by DEETHU alumni, in the field of optics, photonics and optoelectronics.
The Department of Electronic Engineering (formerly the Department of Radio Electronics) of Tsinghua University was established in 1952. Currently it is composed of six Research Institutes, namely, Information Optoelectronic Technology, Information System, Communication, Circuits & Systems, Microwave & Antenna, and Information Cognition & Intelligent System. Our faculty includes two academicians, 49 full professors and 61 associate professors. Meanwhile, we have 1048 undergraduate students and 805 Master and Ph. D candidates.
The Department of Electronic Engineering is one of the earliest institutions in China engaged in teaching and research in electronics and information sciences. Through continuous and concerted research in basic theory, applied technology and system engineering, integrated with plenty of projects from NSFC, National High-Tech Programs and National Key Projects, solid and influential research bases were formed on laser and optics, wireless, networking, and integrated circuits, etc. Academic exchanging programs, joint laboratories and contracted projects were established and performed with renowned universities, research institutes and industries both domestic and abroad. Many outstanding scholars and scientists have been appointed as our honorary or guest professors.
Wafer-scale fabrication of periodic nanostructures with spatially modulated feature sizes is achieved by combining interference lithography and grayscale-patterned secondary exposure, opening new pathways toward large-area nanophotonic devices.
Ultrafast low-pump fluence all-optical modulation for near and mid-infrared wavelengths is demonstrated by enhancing the interaction between graphene and pump/probe light in the nanoscale “hot spots” of graphene-plasmonic hybrid metasurfaces.
Micro-scaled structural color printings are demonstrated by light-programmed, solution-phase, additive manufacturing technique at ambient conditions without complex lithography or etching steps.
This work successfully demonstrates that thin-film lithium niobate platform can bring polarization management devices into a new phase of that higher speed, smaller size, and lower cost.
A thermosensitive optoelectronic upconversion device based on integrated microscale LED and photodiode structures, with temperature dependent of spectral shift and intensity change.
A 1-Pbps orbital-angular-momentum fibre-optic transmission system that combines space-division multiplexing and wavelength-division multiplexing in a 34 km 7-core ring-core fibre is demonstrated utilizing low-complexity 4 × 4 MIMO equalization.
The multiple photonic dopants contained in an epsilon-near-zero medium can serve as non-interacting resonators, and offer an opportunity for the independent control of electromagnetic waves at various frequencies.
