We report error-free transmission of 100 wavelength-division multiplexed (WDM) 10 Gb/s channels with 25 GHz spacing over 400km of non-zero dispersion shifted fiber.

An UDWDM-PON with simple real-time ASK and DPSK transceivers at 6.25 GHZ channel spacing is validated in a field-trial with deployed fiber with power budget above 40 dB.

We demonstrate an FDMA network with up to eight 300 MBd 16QAM subcarriers offering bidirectional 9.6 Gbit/s within a single 12.5 GHz channel.

We demonstrate an FDMA network with up to eight 300 MBd 16QAM subcarriers offering bidirectional 9.6 Gbit/s within a single 12.5 GHz channel.

We introduce an ultra-dense network architecture designed for silicon photonics at the ONU.

We describe the design and implementation of a system for very fast points-to analysis.

We designed an ultra-fast real-time bandwidth-variable transmitter achieving zeropacket loss with ∼10μs switching time, ∼40× faster than previous record.

Dense wavelength division multiplexing optical net-works use tunable devices such as distributed Bragg reflector laser diodes. These optical sources.

We review recent advances in the investigation of vertical cavity saturable absorber devices and their use for the all-optical regeneration of telecommunication signals in ultra-long-haul transmiss

We demonstrate integrated lithium niobate electro-optic modulators with up to 100-GHz electro-optic bandwidth and V_π as low as 1.4 V.
