Real-time Plasma Diagnostic Tool for the investigation of Azimuthal Rotating Instabilities in Hall Effect Thrusters Open
The following paper reports about a non-intrusive diagnostic system able to measure the frequency of azimuthal instabilities inside the discharge channel of Hall Effect Thrusters (HETs) up to several hundreds of kHz in a real-time fashion.…

PBS-Free Polarization-Independent PON Coherent Receiver Open
We introduce a coherent receiver that, without DSP and/or polarization coding at the transmitter, requires no Polarization Beam Splitter and still is polarization-independent. It is experimentally demonstrated at 10 Gbit/s with a sensitivi…

Field-Trial of a High-Budget, Filterless, $\lambda$ -to-the-User, UDWDM-PON Enabled by an Innovative Class of Low-Cost Coherent Transceivers Open
We experimentally demonstrate an innovative ultradense wavelength division multiplexing (UDWDM) passive optical networks (PON) that implements the full λ -to-the-user$ concept in a filterless distribution network. Key element of the propo…

10 Gb/s long-reach PON system based on directly modulated transmitters and simple polarization independent coherent receiver Open
We demonstrate a coherent 10 Gb/s PON system solution exploiting a direct modulated laser (DML) transmitter to obtain long reach (>100 km). The system exploits a simplified coherent receiver. This receiver, which is similar to the scheme t…

4×10 Gb/s coherent WDM-PON system over 110 km of Single Mode Fibre and with 55 dB ODN power budget Open
We experimentally show that, using simplified coherent detection and directly modulated DFB lasers, a 40 Gb/s (4×10 Gbit/s) WDM-PON system can be realized, providing a very high power budget (55 dB) and 110 km reach. This enhances currentl…

Hitless wavelength assignment in filterless optical access networks Open
Advantages offered by coherent detection systems in access networks are not limited to the increase of
\npower budget due to the superior sensitivity. Channel selectivity is another intriguing feature offered by coherent
\nsystems that can…

Polarization-Independent Coherent Real-Time Analog Receiver for PON Access Systems Open
A 1.25-Gb/s ASK passive optical network (PON) system with a -51 dBm pre-FEC sensitivity (at BER = 2 × 10-3) is enabled by a real-time polarization-independent coherent receiver (PI-RX) that needs no DSP (nor ADC). The receiver, which only …
