We propose and analyze a novel physical layer security scheme with the capability of resisting the chosen plaintext attacks in OFDM data transmission. The proposed security scheme consists of a multiple-fold data encryption based on hyper digital chaos, which provides a huge key space. The first chaotic encryption is applied in the chaotic OFDM subcarrier allocation scrambling, both in time and frequency domains. The second encryption is the introduction of chaotic phase rotation of the OFDM signals, where the amount of phase rotation is determining by both of a chaotic sequence and the original input plain data. As a result, it provides a dynamic key system and the generated ciphertexts will be influenced by the original data, which is a core feature against the chosen-plaintext attacks. The proposed security scheme is successfully verified via numerical simulations.

An ultra-compact (coupling length ~ 8.77 micrometer) silicon polarization splitter and rotator is demonstrated based on a bent directional coupler. The peak TM-TE coupling efficiency reaches 96.6%. The crosstalk values are < -1. dB over a wavelength range of 40 nm.
A compact (1.6.4 x 55.1.micrometer2) silicon photonic interleaver is proposed and experimentally demonstrated. The 3-dB and 20-dB bandwidths of the passband are ~1.09 nm and ~1.585 nm, respectively. The central wavele...
A compact (1.6.4 x 55.1.micrometer2) silicon photonic interleaver is proposed and experimentally demonstrated. The 3-dB and 20-dB bandwidths of the passband are ~1.09 nm and ~1.585 nm, respectively. The central wavelength can be changed by tuning only one waveguide.
We show the first field trial of 1.0G-PON with downstream/upstream data rates of 25/1.Gb/s/lambda based on 1.G-class optical devices supporting 40-km reach and 33-dB loss budget. The system stability is verified by 67...

We report a novel silicon MZI switch activated by the phase change of a sub-micrometer-size Ge_2Sb_2Te_5 (GST) thin film. The phase change of GST is triggered by electrical pulses, leading to two "self-holding" switching states. Extinction ratio change of 5-dB is measured from the MZI spectrum.
