Multichannel dispersion compensation using a silicon waveguide-based optical phase conjugator

Abstract

We experimentally demonstrate dispersion compensation using a silicon-based optical phase conjugator. We achieve simultaneous transmission of four dense wavelength division multiplexing (DWDM) channels spaced at 100 GHz and operating at 10 Gbits/s over 320 km of standard fiber. The measured power penalty at bit error rate of 10(-9) is less than 0.3 dB.

Optical phase conjugation using high nonlinearity chalcogenide planar waveguides for dispersion compensation

“…FWM based phase conjugation can be implemented on several platforms such as silica fiber [4][5], SOA devices [15] and silicon waveguides [16]. Recently, chalcogenide glasses have become an attractive nonlinear material due to their desirable properties including ultra-high nonlinearity, fast response time and low nonlinear absorption [7].…”

Multichannel transmission of intensity- and phase-modulated signals by optical phase conjugation using a quantum-dot semiconductor optical amplifier

“…Thus far, a number of transmission experiments based on OPC have been demonstrated using different types of nonlinear elements, such as optical fibers [2], periodically poled lithium niobate [3], chalcogenide glass waveguides [4], silicon waveguides [5], and semiconductor optical amplifiers (SOAs) [6]. However, to the best of our knowledge, no experimental demonstration of OPC using multichannel WDM signals with different modulation formats has been reported yet.…”

“…All-optical signal processing via the nonlinear response of an optical medium to the propagating field power can assist by enabling ultra-fast switching [1], wavelength conversion [2][3][4], regeneration, and performance monitoring [1]. Optical phase conjugation (OPC) is a highlight example, which is capable of compensating both dispersion and nonlinear distortion effects o f optical fi bre transmission [5][6][7][8][9]. It also has the advantages of transparency to the signal bit-rate and data modulation format, and capability to operate on multiple channels of a WDM signal simultaneously [6].…”

“…Recent demonstrations of OPC have focused on developing planar integrated devices [5][6][7][8], which potentially offer a more wavelength fl exible, broadband operation and smaller footprint. This has been demonstrated using both the ∀ (2) nonlinearity in periodically poled lithium niobate (PPLN) [6] and by four-wave mixing (FWM) via the ∀ (3) nonlinearity in semiconductor optical am plifiers [5], silicon [7], and chalcogenide (ChG) glass [8].…”

Planar waveguides also allow the monolithic integration of other components, such as Bragg grating optical filters.…”
