The paper demonstrates a chip scale (4.5 x 4.5 mm2) silicon integrated system that is capable of distributing entangled photons over 160 km single mode fibers without dispersion compensations and external optical filters. The results highlight the potential for massive production and large‐scale deployed quantum integrated circuits for a future ...

A study is presented of four-wave mixing (FWM) in L- and C-band EDFAs. From experiments, it has been observed that FWM scales with the length of Er-doped fibre. It is shown theoretically that FWM crosstalk from EDFAs considerably exceeds that from NZDSF fibre in DWDM L-band systems and leads to a penalty of up to 1 dB in terms of the Q parameter.

SURVEY OF HYBRID EDFA/RAMAN IN C AND L BANDS
Optical amplifiers have had a breakthrough in recent years. Initially, amplification of optical signals was performed passing the optical signal to the electrical domain, then the amplified signal back again to the optical domain.

Waveguide EDFA gain equalisation filter
The authors present a filter designed to flatten the gain of an EDPA system over a 30 nm bandwidth. The filter consists of cascaded couplers and delays, and is fabricated with planar silica waveguides. The design is based on Fourier expansion, and our approach is generally applicable to other complex filters and other waveguide structures.

The effect of amplification on the state of polarization over 50 km using an EDFA [PDF]
This work studies the influence of an Erbium-Doped Fiber Amplifier (EDFA) on the phase variation of light in an optical fiber. To this end, the state of polarization (SOP) was measured as a function of optical power by adjusting the EDFA amplification ...
