Delay Line Optical Recognizer Based On Coherent-To- Chaotic Light Conversion
نویسندگان
چکیده
We demonstrate a delay line optical recognizer at 2.5 Gbit/s. Recognition is based on a coherent-to-chaotic light conversion followed by a fiber array correlation filter. Experimental evidence shows performance improvement in comparison with a classical scheme as far as phase noise is concerned. An experimental characterization of the recognizer is reported. Methods for improving the recognition error probability are suggested.

متن کاملSimultaneous and independent processing of multiple input WDM data signals using a tunable optical tapped delay line.
We demonstrate a tunable optical tapped delay line that can simultaneously and independently operate on multiple wavelength-division multiplexed (WDM) data signals. The system utilizes the wavelength-dependent speed of light, together with nonlinear wavelength conversion stages. A phase-preserving scheme enables coherent addition of the weighted taps. We reconfigured the system to perform separ...
متن کاملHigh-resolution, high-speed photorefractive incoherent-to-coherent optical converter.
We demonstrate a photorefractive incoherent-to-coherent optical converter driven by ultraviolet light that provides a 35-mus response time and an optical resolution of 124 line pairs/mm. The device, implemented in KNbO(3) , operates with a modulating intensity of 85 mW/cm(2) , which corresponds to an optical switching energy per bit of 0.5 pJ. A conversion rate of the order of 90 Gbits/(s cm(2)...
متن کاملUltrafast tuneable optical delay line based on indirect photonic transitions
We introduce the concept of an indirect photonic transition and demonstrate its use in a dynamic delay line to alter the group velocity of an optical pulse. Operating on an ultrafast time scale, we show continuously tuneable delays of up to 20 ps, using a slow light photonic crystal waveguide only 300 μm in length. Our approach is flexible, in that individual pulses in a pulse stream can be con...
