What exactly is Tungsten Selenide
Selenide tungsten (WSe2) (type 2 d material) is a graphene type 2. Its structure is composed the the top layer of selenium/tungsten atom connections between tungstenatoms. This layer has high electrical conductivity, an atomic thickness, fast electron transfers, constraint spin, and is 100000th the size of a diamond. This makes tungsten selenide a versatile material that can be used in many fields, such as photoelectricity, biosensors and supercapacitors. It also has the potential to make solar cells and batteries.
Research significance of photonics
Photonics, a science that examines information carrier with photon, has broad applications prospects in semiconductor laser and optical communication devices, as well as new materials. For the advancement of photonic technology, and for future research into the process of creating photonic devices, it is vital to understand and investigate the photonic generator process.
Tungsten Selenide In Photonic Technology
Researchers discovered that the tungsten selenide was composed of many “co-oscillations”, that are sensitive and responsive to photon absorption. One of WSe2’s oscillations was chosen by the team, which was called D excitons and another pulse (1, 2) was applied. This resulted in one of the two pulses switching to an A exciton while the other pulse (1, 2) was changed to an A exciton. Their sum frequency (1+2) was then switched to A D exiton with an A signal that was 20 times greater than the single resonant. SFG produces photons with a higher intensity than SHG.
These are just a few of the many benefits that advanced photonic devices have. Not only does the double resonance SFG technique provide new scientific methods for microscopic, nonlinear spectral, and optical analysis but it also allows for new nonlinear optics techniques and nonlinear optometry using two-dimensional semiconductors. These researches have the potential of bringing photonics up to a higher level, such that medical care can be provided with more advanced optical imaging equipment and less expensive diagnostic methods.
