New type of non-volatile high-speed optical memory is proposed, which utilize the magnetization reversal of nanomagnet by spin-polarized photo-excited electrons. To verify high speed of proposed demultiplexing method, the switching of spin polarization at 2.2 TGz was demonstrated.
We report an efficient technique to measure gain and losses of quantum cascade lasers (QCLs). It consists on the analysis of the Fabry-Perot fringes induced by the optical injection of a chirped distributed feedback QCL.
Continuous channel waveguides in periodically poled KTiOPO4 with guided orthogonal polarizations are used to demonstrate type-II background-free second harmonic generation at 1505 nm with 1.2 %/(W cm2) normalized efficiency.
We present a new technique to coherently control ultrafast nonlinear processes in a plasmonic nanostructure on a femtosecond timescale. By using a four-photon process our detection provides full information about the coherence in the system.
The field of optics is finding myriad applications in information technology, health care, lighting, sensing and national security. This paper explores the role of nanotechnology with special focus on nanophotonics in dielectric and inhomogeneous metamaterials with applications for optical information processing in space and time, communications, and sensing.
We demonstrate the spontaneous Raman effect in suspended InGaAsP waveguides and report that the zinc blende Raman selection rules are relaxed in the waveguide geometry. The suspended semiconductor waveguide is an exciting platform for a range of linear and nonlinear optical experiments due to its enhanced light-guiding capability.
We designed a silicon microring based elastic polarization converter, which can realize arbitrary polarization conversion between any two of linear, circular, and elliptic polarization states. Simulation results show good polarization converting characteristics at resonance condition.
Here we demonstrate two novel approaches to on-chip optofluidic transport. We show the trapping of polystyrene microspheres using SU-8 waveguides down to 75 nm polystyrene nanoparticles and linear lambda-DNA using silicon slotted waveguides.
We demonstrate a silicon-organic hybrid waveguide fabricated by vapor deposition of a small molecule with a large third-order nonlinearity on a silicon-on-oxide slotted waveguide. The resulting organic cladding has a high third-order susceptibility, high optical quality, and it homogenously fills the slot where the optical mode propagates.
