Title:

OPTICAL LOGIC GATE

Document Type and Number:

WIPO Patent Application WO/2010/058432

Kind Code:

A8

Abstract:

Optical logic gate (1) having a second -harmonic generator element (15) that receives a first (sii) and a second optical input signal (si2) respectively having a first (ω1) and a second angular frequency (ω2) and respectively having a first (P; S) and a second (P; S) polarization, and which provides a second-harmonic optical signal (su3) having a third angular frequency (2ωi, ω1+ω2) and a third (P; S) polarization. The third angular frequency (2ωi, ω1+ω2) is equal to the sum of the first (ω1) and the second angular frequency (ω2). The third (P; S) polarization is a function of the first (P; S) and the second (P; S) polarization. The second-harmonic generator element (15) includes a second-harmonic generator layer (22) in a material having a non-null second-order optical tensor.
