We present a first high performance APD-based linear burst-mode receiver (BM-RX) with a record wide dynamic range of 31dB. The APD multiplication factor is controlled from burst to burst within 60ns by an on-chip self-generated M-control signal. Introduction Passive optical network (PON) systems are widely used to create cost-effective optical access network and will play an increasingly important role in future access networks. Some recent research focused on upgrading existing PON systems with extended reach and 1 increased splitting ratio . Extending the link reach enables rural subscriber services while maintaining the PON's cost benefits, and increasing the splitting ratio allows offering services to urban subscribers with reduced number of optical line terminals (OLTs). Although the majority of existing OLTs employ a BM-RX using a limiting amplifier, the link reach can be extended using an APD-based linear BM-RX, which allows efficient use of 2 electronic equalization . As the link reach is extended, the possible difference between upstream burst signal intensities from different ONUs is also increased. Therefore, not only high receiver sensitivity but also wide dynamic range is of important consideration for the requirements of the proposed APD linear BMRX. The APD-based solution allows the linear BM-RX to operate without an optical preamplifier and the bias-dependent multiplication factor (M) adds another degree of freedom for increasing the linear range. The EDFA pre3 amplified PIN-based linear BM-RX demonstrated its operation with electronic dispersion compensation (EDC) with a 22.7dB 4 dynamic range.

Based on the physical model of a bulk reflective semiconductor optical amplifier (RSOA) used as a modulator in radio over fiber (RoF) links, the distributions of carrier density, signal photon density, and amplified spontaneous emission photon density are demonstrated. One of limits in the use of RSOA is the lower ...

How to preserve users' privacy while supporting high-utility analytics for low-latency stream processing? To answer this question: we describe the design, implementation and evaluation of PRIVAPPROX, a data analytics system for privacy-preserving stream processing. PRIVAPPROX provides three properties: (i) Privacy: zero-knowledge privacy (ezk) guarantees for users, a privacy bound tighter ...
