We demonstrate all-optical 2R regeneration with a 90° optical hybrid and integrated MZI-SOA pairs for 10 Gb/s BPSK and 20 Gb/s QPSK with negative power penalty. Power penalty and OSNR improvements of ...
We present a FWM-based dual channel wavelength converter in an SOA with very small variations in conversion efficiency and a minor polarization related power penalty of 0.9dB between best and worst ca...
We propose and demonstrate a novel ring-based WDM/TDM-PON architecture which can flexibly concentrate subscribers in response to the demand. A wavelength converter and an injection-locked Fabry-Perot ...
We achieved the first integration of a QPM wavelength converter with an MMI multiplexer by using a direct-bonded LiNbO 3 ridge waveguide. We successfully demonstrated high quality grouped wavelength c...
We propose an all-optical XOR gate using integrated SOA three-arm-MZI wavelength converter and experimentally demonstrate an error-free operation converting from two NRZ-OOK signals to one RZ-OOK sign...
In this paper, we present our researches on the applications of periodically poled lithium niobate (PPLN) in optical communications. Tunable wavelength converter and filter are investigated based on P...
This paper evaluates the balance between the cost of multifibres and the cost of wavelength converters in multilayer networks. A novel ILP formulation of the static planning problem is applied.
We demonstrate 40 Gb/s SOA-based wavelength conversion from a RZ into a vestigial-sideband RZ signal. SOA related pattern effects are successfully suppressed by proper choice of the red-shift optical ...
An all-optical wavelength converter is demonstrated using an InP micro-disk laser on SOI. In this configuration, no extra probe beam is needed. The control power is as low as several micro-watts.
We demonstrate a monolithic wavelength converter based on a PD-EAM optical gate and tunable SGDBR laser operating at any bit rate up to 40 Gb/s in both NRZ and RZ formats.
