Phys.org August 21, 2024 Existing optical switching solutions are inadequate for addressing flexible information exchange among the mode channels. Researchers in China introduced a flexible mode switching system in a multimode fibre based on an optical neural network chip. The system utilized the flexibility of on-chip optical neural networks along with an all-fibre orbital angular momentum (OAM) mode multiplexer-demultiplexer to achieve mode switching among the three OAM modes within a multimode fibre. They validated the system by successfully transmitting different modulation formats across various modes. According to the researchers their system could provide effective optical switching in practical multimode communication […]

Optical switching at record speeds opens door for ultrafast, light-based electronics and computers
Science Daily March 22, 2023 Recently, optical switches have been demonstrated using terahertz and ultrafast laser pulses to control the electrical signal and enhance the switching speed to the picosecond and a few hundred femtoseconds time scale. An international team of researchers (USA- University of Arizona, Ohio State University, Germany) used the reflectivity modulation of the fused silica dielectric system in a strong light field to demonstrate the optical switching (ON/OFF) with attosecond time resolution. They presented the capability of controlling the optical switching signal with complex synthesized fields of ultrashort laser pulses for data binary encoding. AccrdingAccording to the […]
