Latest Patents

Raffy's latest patents include a monomode optical source and an optical amplifying device that is tuneable. The optical source and device feature a generator of a pump wave, along with optical means for coupling with a monomode optical fiber. This design allows for the guiding and highly confining of the pump wave, creating a four-photon nonlinear interaction. Additionally, at least one section of the optical fiber is housed in a thermostat-controlled enclosure, which is associated with a temperature control device. This setup enables continuous tuning across a range of frequencies within the near-infrared spectrum. Another significant patent involves Langmuir-Blodgett films that are usable in nonlinear optics. These films consist of at least one layer of amphiphilic molecules of two different types. The first type includes molecules that are active in nonlinear optics, while the second type consists of either inert molecules or those that are also active. The specific mixture of these two types of molecules results in a film capable of radiating an optic wave that is a second harmonic in relation to an exciting wave.
