Abstract
Official abstract text for this publication.
A technique is provided for modulating light in a telecommunication network. The technique includes modulating light with a first intensity modulator and modulating light with a second intensity modulator. The first intensity modulator and the second intensity modulator are applied a mutual angular phase shift. The mutual angular phase shift is non-orthogonal and non-PI/2-dividable.
First claim
Opening claim text (preview).
1 . A method of modulating light in a telecommunication network, comprising: modulating light with a first intensity modulator on a first branch; and modulating light with a second intensity modulator on a second branch, the first branch and the second branch being parallel to each other, the first intensity modulator and the second intensity modulator being applied a mutual angular phase shift, wherein the mutual angular phase shift is non-orthogonal and non-PI/2-dividable. 2 . The method according to claim 1 , wherein the mutual angular phase shift is strictly comprised between PI/2 and PI in absolute values. 3 . The method according to claim 1 , wherein the mutual angular phase shift is comprised between 7PI/12 and 3PI/4 in absolute values. 4 . The method according to claim 1 , wherein the mutual angular phase shift is sensibly equal to 2PI/3 in absolute value. 5 . The method according to claim 1 , further comprising modulating light with a third intensity modulator. 6 . The method according to claim 5 , wherein the third intensity modulator is applied an angular phase shift in reference to the first intensity modulator which is comprised between 7PI/12 and 3PI/4 in absolute values. 7 . The method according to claim 6 , wherein the third intensity modulator is applied an angular phase shift in reference to the first intensity modulator which is sensibly equal to 2PI/3 in absolute values. 8 . An optical modulating component comprising: a first branch on which a first intensity modulator is placed; and a second branch on which a second intensity modulator is placed, the first branch and the second branch being parallel to each other, the first intensity modulator and the second intensity modulator being applied a mutual angular phase shift, wherein the mutual angular phase shift is non-orthogonal and non-PI/2-dividable. 9 . The optical modulating component according to claim 8 , further comprising an integrated circuit in which the first intensity modulator and the second intensity modulator are integrated. 10 . The optical modulating component according to claim 8 , wherein the mutual angular phase shift is strictly comprised between PI/2 and PI in absolute values. 11 . The optical modulating component according to claim 8 , wherein the mutual angular phase shift is comprised between 7PI/12 and 3PI/4 in absolute values. 12 . The optical modulating component according to claim 8 , wherein the mutual angular phase shift is sensibly equal to 2PI/3 in absolute value. 13 . The optical modulating component according to claim 8 , further comprising a third intensity modulator. 14 . The optical modulating component according to claim 8 , further comprising a laser component. 15 . A telecommunication network comprising an optical modulating component according to claim 8 .
