CONSTITUTION:The light absorptive dye and the electron receptor or electron donor are dispersed into the supporting material and the free energy change DELTAG of the electron transfer reaction is specified to >=-2.0eV; in addition, the recording is executed by the stepwise two photon stimulation....
Ideally, wavelength conversion can be achieved by accelerating photoabsorbed charges through this giant built-in electric field with a very high mobility. However, efficient wavelength conversion was not possible before due to the very shallow band bending at the surface of the semiconductor, which ...

In this example, the wavelength will be equal to 29.98 m. You can also use this tool as a frequency calculator. Simply type in the values of velocity and wavelength to obtain the result. Remember that the frequency doesn't change when passing from one medium to another. If you are ...
PROBLEM TO BE SOLVED: To provide a wavelength converting device that is capable of converting wavelength of a laser light signal modulated at a rate higher than several Gb/s, by preparing a laser resonator in which plural active medium regions are distributed, and a waveguide from which a ligh...

1.2.2.1 Change in wavelength during degradation The lasing wavelength of laser diodes is basically determined with the band gap of the active layer in Fabry–Perot types and the refractive index in DFB and distributed Bragg reflector (DBR) types, as shown in Figure 1.8 (Fukuda et al. 2010)....
