A waveguide middle-infrared electro-optic modulator working at room temperature is demonstrated. It contains only six quantum wells. A reverse biased Schottky diode is used to deplete the electronic population in quantum wells and to modulate the int

We present a theoretical and experimental study of parametric generation in a guided wave quasi-phase-matched configuration. A numerical model taking into account inverted domain shape, electrooptic and photorefractive effects, as well as waveguide p

Quasi-phase-matched second-harmonic generation efficiency in periodically poled LiNbO/sub 3/ using titanium indiffusion, has been theoretically investigated. This permits clarifying how the involved guided modes convert the triangle-shaped form of th

Mid-infrared ( approximately 10 mu m) electrorefractive effects of intersubband transitions in step GaAs/GaAlAs quantum wells are experimentally analyzed. A method for studying infrared electrorefraction of a two-dimensional structure via the Stark e

We report the realization of the first self-frequency-doubled waveguide laser. The structure is based on a high Δ n proton exchange waveguide in z -cut Nd:MgO:LiNbO 3 which leads to new lasing wavelengths in the material. Two types of self-doubled h

We give experimental results for amplitude and phase modulation by free-carrier injection in planar and rib waveguides at a wavelength of 10.6 microm. These waveguides have been formed by metal-organic chemical-vapor deposition of InP and GalnAs laye

We show that the averaged second‐harmonic conversion efficiency of quasi‐phase‐matched LiTaO3 waveguides can be increased by a factor larger than 15 with the use of single‐mode pulsed AlGaAs laser diodes as the optical sources. The proton exc

Second harmonic generation (SHG) in waveguides which are multimode at the second harmonic exhibit an intensity dependence in both the phase‐match wavelength and relative conversion efficiency of the different SHG modes because they are coupled to t
