Title (EN) SILICON-BASED ELECTRO-OPTIC PHASE MODULATOR WITH REDUCED RESIDUAL AMPLITUDE MODULATION
(FR) MODULATEUR DE PHASE ELECTRO-OPTIQUE A BASE DE SILICIUM A MODULATION D'AMPLITUDE RESIDUELLE REDUITE
Abstract: front page image
(EN)An arrangement for removing unwanted amplitude modulation from the output of an electro-optic phase modulator (formed within a silicon-on-insulator (SOI) system) includes resonant filters that are biased on the positive and negative slopes of the response signal. Therefore, as the amplitude response of one filter decreases, the amplitude response of the other filter increases, resulting in balancing the output and essentially eliminating amplitude modulation from the phase-modulated output signal. In one embodiment, ring resonators (formed in the SOI layer) are used to provide the filtering, where as the number of resonators is increased, the performance of the filtering arrangement is improved accordingly.
(FR)L'invention concerne un moyen permettant d'éliminer une modulation d'amplitude indésirable de la sortie d'un modulateur de phase électro-optique (formé dans un système de silicium sur isolant (SSI)), comprenant des filtres résonants qui sont polarisés au niveau des pentes positives et négatives du signal de réponse. Par conséquent, plus la réponse en amplitude d'un filtre baisse, plus la réponse en amplitude de l'autre filtre augmente, ce qui permet d'équilibrer la sortie et d'éliminer sensiblement la modulation d'amplitude du signal de sortie modulé en phase. Dans un mode de réalisation, des résonateurs en anneau (formés dans la couche SSI) sont utilisés pour obtenir le filtrage. Ainsi, plus le nombre de résonateurs est grand, meilleures sont les performances de filtrage.
