The modulation bandwidth of silicon-based photonics is limited to approximately 60 GHz because of the maximum carrier mobility,which limits its development in high-capacity and high-speed information *** niobate has received much attention due to its excellent electro-optic properties.
We investigate a "Voigt laser"at Cs-D2 resonance line 852 nm using a Voigt anomalous dispersion optical filter (VADOF) as frequency-selecting element. The wavelength of the Voigt laser is stabilized within t...
