WUHAN, China (May 11, 2017) - Wuhan Optoelectronics Forum No. 119 was successfully held in Auditorium A101 at Wuhan National Laboratory for Optoelectronics (WNLO) in the morning of May 11. Prof.

20170623 Investigation on helical long period grating on multicore fiber with CO2 splicer and sensor application

Long-period gratings (LPGs) serve as components in optical fiber sensors, filters, and fiber lasers. Most LPGs are fabricated with CO2 or excimer lasers. Most fabrication methods attempt to induc

20170608 Fabrication of metal/semiconductor nanocomposites by selective laser nano-welding

Nanocomposites are of great interest due to their novel properties that originated from the synergic effect. Current approaches are not cost-effective and eco-friendly because of the usage of tox

20170526 Single hole twin eccentric core fiber sensor based on anti-resonant effect combined with inline Mach-Zehnder interferometer

Simultaneous measurement for multi-parameters and avoiding the cross interference of the external environment temperature based on the fiber sensor has been widely investigated in recent years du

20170509 Bandwidth adaptable photonic differentiator employ a slow light effect

As a crucial building block of the photonic integrated circuit (PIC), a photonic differentiator (DIFF) plays one of the key roles in analog optical signal processing due to its functionality

20170510 A novel, energy-efficient on-chip optical diode

On-chip optical nonreciprocal devices have always been the fundamental problems in an integrated optical communication system. Just like the diode in an electric system, it allows light to pass in a d

Photodetector can convert optical signals into electrical signals, therefore they are widely used in imaging, remote sensing, spectroscopy, and other fields. Traditional photoconductive photodete

20170417 The exceptional points in integrated metal and graphene metamaterials

In an open quantum system with parity-time symmetry, the Hamiltonian is non-Hermitian but possesses purely real eigenvalues. Once the parity-time (PT) symmetry is broken, the eigenvalues are no longer
