Performance Analysis of Six Electro-Optical Crystals in a High-Bandwidth Traveling Wave Mach-Zehnder Light Modulator

Photonics
In this study, a traveling wave Mach-Zehnder intensity modulator (TW-MZM) was designed and optimized for six different electro-optical (EO) crystals: lithium niobate (LNB), potassium niobate (KNB), lithium titanate (LTO), beta barium borate (BBO ...

Entangling two distant nanocavities via a waveguide

, 2011
In this paper, we investigate the generation of continuous variable entanglement between two spatially-separate nanocavities mediated by a coupled resonator optical waveguide in photonic crystals.

Testing nonlinear electrodynamics in waveguides: the effect of magnetostatic fields on the transmitted power [PDF]

, 2010
In Born-Infeld theory and other nonlinear electrodynamics, the presence of a magnetostatic field modifies the dispersion relation and the energy velocity of waves propagating in a hollow waveguide.

Terahertz Waveguide Prism

Advanced Photonics 2013, 2013
We present an easily fabricated waveguide prism for the terahertz (THz) frequency range. The prism is made of polypropylene and uses waveguide dispersion to spatially separate frequencies over the range of 0.1 to 0.7 THz. The diffraction properties of the prism were determined using electromagnetic field simulations and the waveguide parameters were ...

Reverse Ridge Silicon Strip Waveguide and Silica Slot Waveguide Structure for the Dispersion at 1550 nm

IEEE Photonics Journal, 2016
We have proposed a reverse ridge strip waveguide and a slot waveguide structure for the dispersion compensation at 1550 nm wavelength. The resonance between strip- and slot-waveguide modes has been used to calculate the dispersion at the required ...

Second-Harmonic Generation in Suspended AlGaAs Waveguides: A Comparative Study

Micromachines, 2020
Due to adjustable modal birefringence, suspended AlGaAs optical waveguides with submicron transverse sections can support phase-matched frequency mixing in the whole material transparency range, even close to the material bandgap, by tuning the width-to ...

Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

Advanced Functional Materials, EarlyView.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential
