We compare three feedforward non-data-aided clock recovery algorithms suitable for burst-mode reception in PONs and datacenters. Our experimental setup allows real-time OOK transmission at 3 Gbit/s. The tolerable clock frequency mismatch is 475 ppm.

We propose a novel coherent TWDM PON architecture. Using a chip-scale QD-MLLD and low-cost thermally tuned DFB lasers, we demonstrate error-free reception of 80 Gb/s at a loss budget of 28 dB with ONU laser variation of 2 nm (0.25 THz).

We propose a colorless coherent PON architecture alleviating the need for wavelength locking of the ONU lasers. Using two different types of comb sources, we demonstrate error-free reception at −25 dBm received power over bandwidths of 600 GHz and

Single Electron Transistor (SET) is an ultra small device which can be used as a possible replacement of a MOSFET. Like CMOS technology, CSET (Complementary SET) models can be used to build same digital circuits. Apart from the drawbacks (which have
