چکیده
We experimentally demonstrate a tunable optical correlator to search for multiple patterns among QPSK symbols. We utilize an optical frequency comb to generate the coherent signals and multiplex them coherently in a single PPLN waveguide. Multiple patterns with different lengths are successfully searched within QPSK symbols in a 40-Gb/s signal.

Tunable Optical Correlator using an Optical Frequency Comb for Generating Multiple Taps in a Tapped-Delay-Line Composed of a Single Nonlinear Element
We experimentally demonstrate a tunable optical correlator to search for multiple patterns among QPSK symbols in 20 Gbuad stream. We use an optical frequency comb to generate coherent signals and add them coherently using a single PPLN waveguide. Multiple patterns with different lengths are successfully searched on QPSK signals.
متن کاملTunable radio frequency photonics filter using a comb-based optical tapped delay line with an optical nonlinear multiplexer.
A radio frequency (RF) photonic filter is experimentally demonstrated using an optical tapped delay line (TDL) based on an optical frequency comb and a periodically poled lithium niobate (PPLN) waveguide as multiplexer. The approach is used to implement RF filters with variable bandwidth, shape, and center-frequency.
متن کاملAll-Optical Reconfigurable-Tunable 1×N Power Splitter Using Soliton Breakup
In this paper, we numerically simulated a glass-based all-optical 1×N power splitter with eleven different configurations using soliton breakup in a nonlinear medium. It is shown that in addition to reconfigurability of the proposed splitter, its power splitting ratio is tunable up to some extent values too. Nonlinear semivectorial iterative finite difference beam propagation method (IFD-...
متن کاملOptical Nyquist channel generation using a comb-based tunable optical tapped-delay-line.
We demonstrate optical Nyquist channel generation based on a comb-based optical tapped-delay-line. The frequency lines of an optical frequency comb are used as the taps of the optical tapped-delay-line to perform a finite-impulse response (FIR) filter function. A single optical nonlinear element is utilized to multiplex the taps and form the Nyquist signal. The tunablity of the approach over th...
متن کاملReconfigurable 2-D WDM Optical Tapped-Delay-Line to Correlate 20Gbaud QPSK Data
We demonstrate a 2-D optical tapped-delay-line that exploits nonlinearities and chromatic dispersion to perform 2-D correlation on 20Gbaud QPSK data with correlator results with an average EVM of ~7.8%. We successfully recognize different 2×2 target patterns in an image with 961 pixels. Introduction Correlators are useful building blocks for various applications, including data decoding and pat...
