Analytical Study of Sub-Wavelength Imaging by Uniaxial Epsilon-Near-Zero Metamaterial Slabs
Analytical Study of Sub-Wavelength Uniaxial Epsilon-Near-Zero Metamaterial Slabs Optics
2012/5/29
We show that the two-dimensional Green's function of a uniaxial (with possibly tilted optical axis) epsilon-near-zero metamaterial slab, of interest for sub-wavelength imaging, can be calculated analy...
25 kHz narrow spectral bandwidth of a wavelength tunable diode laser with a short waveguide-based external cavity
25 kHz narrow spectral bandwidth wavelength tunable diode laser short waveguide-based external cavity Optics
2012/4/19
We report on the spectral properties of a diode laser with a tunable external cavity in integrated optics. Even though the external cavity is short compared to other small-bandwidth external cavity la...
We report a wavelength-interleaving bidirectional circulator, in which the even and odd ITU channels circulate in opposite handedness. Demonstrated three-port bidirectional isolation ranges from 45 dB...
Abstract—This work presents a novel wavelength conversion scheme, differential cross-polarization modulation (DXPoM), using an extra birefringence delay to enhance the performance of the conventional ...
Manipulating optical signals at sub-wavelength scale by planar arrays of metallic nanospheres: Towards plasmonic interference devices
optical signals sub-wavelength scale metallic nanospheres plasmonic interference devices
2011/8/18
Abstract: We show that interference can be the principle of operation of an all-optical switch and other nanoscale plasmonic interference devices (PIDs). The optical response of two types of planar pl...
Third and fifth harmonics generation by tightly focused femtosecond pulses at 2.2 μm wavelength in air
harmonics focused femtosecond pulses
2011/9/6
We report experiments on the generation of third and fifth harmonics of millijoule-level, tightly focused, femtosecond laser pulses at 2.2 μm wavelength in air. The measured ratio of yields of the thi...
We demonstrate a stable CMOS-compatible on-chip multiple-wavelength source by ltering and modulating individual lines from a frequency comb generated by a microring resonator optical parametric oscil...
Wavelength tunable spectral compression in a dispersion-increasing fiber
Wavelength dispersion-increasing fiber
2011/8/26
Adiabatic soliton spectral compression in a dispersion-increasing fiber is demonstrated both numerically and experimentally.We show a positively-chirped pulse provides better spectral compression in a...
Dynamic of rescattering-electron wave packets in strong and short-wavelength laser fields: Roles of Coulomb potential and excited states
scattering-electron wave packets in strong short-wavelength laser fields Coulomb potential excited states
2014/5/28
We investigate the high-order harmonic generation of atoms and molecules exposed in strong and shortwavelength (shorter than 800 nm) laser fields. Our simulations show that the electronic rescattering...
Contribution of interband effects caused by long-wavelength transverse optical phonons to electron-phonon coupling in doped polar insulators
Contribution of interband effects electron-phonon coupling doped polar insulators
2010/11/22
We estimate the contribution of the long-wavelength el–TO–ph interaction and discuss the effect it has on electron pairing in doped polar systems like SrTiO3 and PbTe. The analytical and numerical res...
Optical-Wavelength Paramagnetic Phaser (Lecture Notes). Section 3.1. Nonlinear Balance Equations of Motion
Optical-Wavelength Paramagnetic Phaser Nonlinear Balance Equations class-B lasers
2010/4/1
In this work I present a detailed description of the simplest nonlinear model for an optical wavelength paramagnetic phaser, which is an acoustic analog of the class-B lasers. Despite of its simplicit...
