Emerging symmetric 10Gb/s passive optical network (PON) systems aim at high network transmission efficiency by reducing the RX settling time that is needed for RX amplitude recovery in burst-mode (BM). A conventional AC-coupled BM- RX has an inherent tradeoff between short settling time and decision threshold droop, which makes an RX settling time shorter than 400ns hard to achieve. Some techniques have been developed to overcome this limitation, demonstrating a settling time of 150 to 200ns. Our previous work uses feed-forward automatic offset compensation (AOC) to achieve a response time as short as 25.6ns. However, a feed-forward scheme using peak detectors is intrinsically less accurate and results in relatively high power consumption. In this paper, we present a DC-coupled 10Gb/s BM-TIA and burst-mode limiting amplifier (BM- LA) chipset that uses a feedback type AOC circuit with switchable loop BW. This new technique is capable of removing input DC offset in less than 75ns, and offers continuous decision threshold tracking during payload, to cope with the maximum length of CID. The differential TIA output port senses a CM reset signal provided by the succeeding BM-LA, and activates an on-chip reset and lock function. This BM-LA also integrates auto reset/activity generation circuits providing the AOC BW switching signal, so that this time-critical signal is not required from the PON system.

This paper presents a 10 Gb/s avalanche-photodiode-based DC-coupled reshaping and reamplifying (2R) burst-mode receiver with on-chip auto-reset generation and multiple data rate support, designed for 10G-GPONs. A short 2R settling time of 75 ns (150 ns for lower-rate operation), a high receiver sensitivity of -31.3 dBm, and a large loud/soft ratio of 25.3 dB are demonstrated at 2.5/5/10 Gb/s in burst-mode operation. Allowing multi-rate operation without external reset signals, it shows great potential for use in emerging symmetric 10G-GPON systems and allows for more flexible future optical access networks.

This paper presents a chain of four fully DC-coupled 10Gb/s burst-mode prototypes operating with 58ns overhead for the first time. 10Gb/s upstream burst-mode experiments are performed without a time-critical reset signal from test equipment.

This paper reports a high performance DC-coupled 10Gbit/s optical burst-mode receiver for symmetric 10G-GPONs. The measured receiver sensitivity is −30.0dBm at BER=10<sup>−3</sup> within a short settling time of 51ns, and a loud/soft ratio wider than 24.0dB.

The Extreme Ultraviolet Imager (EUI) on-board the Solar Orbiter mission will provide image sequences of the solar atmosphere at selected spectral emission lines in the extreme and vacuum ultraviolet. For the two Extreme Ultraviolet (EUV) channels of the EUI instrument, low noise and radiation tolerant detectors with low power consumption and high sensitivity in the 10-40 nm wavelength range are required to achieve the science objectives. In that frame, a dual-gain 10 μm pixel pitch back-thinned 1k x 1k Active Pixel Sensor (APS) CMOS prototype has been tested during the preliminary development phase of the instrument, to validate the pixel design, the expected EUV sensitivity and noise level, and the capability to withstand the mission radiation environment. Taking heritage of this prototype, the detector architecture has been improved and scaled up to the required 3k x 3k array. The dynamic range is increased, the readout architecture enhanced, the power consumption reduced, and the pixel design adapted to the required stitching. The detector packaging has also been customized to fit within the constraints imposed by the camera mechanical, thermal and electrical boundaries. The manufacturing process has also been adapted and back-thinning process improved. Once manufactured and packaged, a batch of sensors will undergo a characterization and calibration campaign to select the best candidates for integration into the instrument qualification and flight cameras. The flight devices, within their cameras, will then be embarked on the EUI instrument, and be the first scientific APSCMOS detectors for EUV observation of the Sun.

A burst mode receiver designed for 10G-GPON systems was tested in a packet-optical add/drop multiplexer metro network. Fast power dynamic range and OSNR tolerance recordings demonstrate that this receiver is compliant with metro network requirements.
