We demonstrate 10 Gb/s, 5-channel, wavelength multiplexed transmission over four 80-km standard fiber spans using polarization invariant spectral inversion provided by a broad-band fiber parametric

We describe a photonic integrated circuit composed of three 1.5 micron wavelength multiple quantum well tunable lasers with a passive optical power combiner and an optical output amplifier.

For TWDM-PON systems we report measurements and mitigation methods for the unwanted wavelength drift of directly modulated burst-mode lasers.

We propose and demonstrate a multiple exposure lithographic technique that is wavelength independent.

A new technique is presented for seamlessly upgrading an existing passive optical network (PON) to a higher bitrate on a different wavelength without the need to retrofit any of the existing legacy

We demonstrate wavelength locking in a widely-tunable fast-switching laser module that accesses 64 ITU channels with 50 GHz spacing and switches wavelength in under 50 ns.

We demonstrate wavelength locking in a widely-tunable fast-switching laser module that accesses 64 ITU channels with 50 GHz spacing and switches wavelength in under 50 ns.

Different types of available circuits are analysed and compared, and problems of coupling to the source to be measured, as well as the necessary indicating apparatus, are outlined.

Wavelength re-routing has been suggested as a viable and cost effective method to improve the blocking performance of wavelength-routed Wavelength-Division Multiplexing (WDM) networks.

We present a reconfigurable wavelength-selective switch that independently distributes 128 input WDM channels to four output ports.
