A compact (106.4 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 (106.4 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.
The continuous-variable version of quantum key distribution (QKD) offers the advantages (over discrete-variable systems) of higher secret key rates in metropolitan areas, as well as the use of standard telecom compone...

We show the first field trial of 100G-PON with downstream/upstream data rates of 25/10Gb/s/lambda based on 10G-class optical devices supporting 40-km reach and 33-dB loss budget. The system stability is verified by 67-hour real-time BER measurement.
Modal dispersion is one of the key impairments for few-mode fiber transmission. We propose a modified equalization method for CO-SCFDE system, which has better tolerance to modal dispersion and slightly increased comp...
