Data-aided algorithms for coherent optic receivers are discussed as an extension of existing non-data aided methods. The concept presents a scalable approach with low implementation complexity and limited overhead for higher-order modulation formats.

We present results with different nanopatterning techniques using table top extreme ultraviolet lasers. The three approaches are interferometric lithography, Talbot self imaging and holographic projection lithography.

Strong bandwidth-enhancement has been observed in GaAs/AlGaAs UTC-PD under small-output-photocurrent (0.4 mA) and zero-bias operation. Equivalent-circuit-modeling results indicate that such effect is due to self-induced-field inside absorption layer, which benefits devices' high-speed performance under zero-power-consumption operation.

We present a comparison between an in-held and an in-laboratory 50 km ultralong erbium-doped fiber lasers operating in active mode-locking regime. The results show better performance of the in-laboratory laser with pulses from 36.1 to 97.3 ps with repetition rate from 1 to 10 GHz.

We demonstrate a 10 Gb/s symmetrical WDM-PON exploiting a cross seeding scheme to enable wavelength reusing. It avoids reflection-induced penalties, and effectively removes any extinction-ratio constraint by means of DPSK modulation format in the downlink.
