High-speed Fading-free Direct Detection for DoubleSideband OFDM Signal via Block-wise Phase Switching
High-speed Fading-free Direct Detection Double Sideband OFDM Signal Block-wise Phase Switching
2014/11/6
We employ phase switching of either main-carrier or subcarriers of two consecutive signal blocks for double-sideband fading-free direct-detection (DD). In so doing, 40-Gb/s DDOOFDM is successfully rec...
Non-reciprocal phase shift induced by an effective magnetic flux for light
Non-reciprocal phase shift induced effective magnetic
2015/8/6
Photons are neutral particles that do not interact directly with a magnetic field. However, recent theoretical work1,2 has shown that an effective magnetic field for photons can exist if t...
Phase-Matching and Parametric Conversion for the Mid-Infrared in As2S3 Waveguides
As2S3 Mid-Infrared Phase-Matching Four-Wave Mixing
2013/1/30
We illustrate two As2S3 waveguide designs for four-wave mixing, which can generate 3.03 μm mid-infrared light from a 1.55 μm near-infrared signal source and a 2.05 μm pump source. Through simulations,...

Coherent Detected Secure Point-to-Point Optical Fiber Transmission Ultra-Dense Optical Spectral Phase Coding Multilevel BCJR Equalization
2016/12/2
A secure P2P optical fiber communication scheme based on ultra-dense optical spectral phase coding (UD-SPC) is proposed. The multi-code interference is suppressed by increasing the memory of the multi...
Temperature Dependence of the Raman Intensity and the Bandwidth Close to the Order-Disorder Phase Transition in NaNO3
Raman Intensity Bandwidth NaNO3
2013/1/30
We analyze the temperature dependence of the Raman intensity using the experimental data according to a power-law formula close to the order-disorder transition (Tc = 549 K) in NaNO 3. From this analy...
Realizing effective magnetic field for photons by controlling the phase of dynamic modulation

2015/8/7
The goal to achieve arbitrary control of photon flow has motivated much of the recent research on photonic crystals and metamaterials. As a new mechanism for controlling photon flow, we in...
Information Encryption Based on Using Arbitrary Two-Step Phase-Shift Interferometry
Deterministic Phase-Encoded Encryption Arbitrary Two-Step Phase-Shift Interferometry Lenticular Lens Array
2013/1/30
A deterministic phase-encoded encryption system is proposed. A lenticular lens array (LLA) sheet with a particular LPI (lenticular per inch) number is chosen as a modulator (key) instead of the random...
