DUAL-POLARIZATION ROTATIONALLY-INSENSITIVE MONOSTATIC TRANSCEIVER WITH DUAL CLADDING FIBER

An apparatus (300) includes multiple dual cladding waveguides (222, 240) each having a single-mode interior section (220, 230) that transports one of multiple outgoing optical signals and a multimode section (228, 238) at least partially surrounding the interior section (220, 230) that transports on...

Zusammenfassung:	An apparatus (300) includes multiple dual cladding waveguides (222, 240) each having a single-mode interior section (220, 230) that transports one of multiple outgoing optical signals and a multimode section (228, 238) at least partially surrounding the interior section (220, 230) that transports one of multiple incoming optical signals (216a-216b). Different outgoing signals (214a-214b) have different polarizations, and different incoming signals (216a-216b) have different polarizations. The apparatus also includes a polarization beamsplitter (206) that combines the multiple outgoing signals (214a-214b) to produce transmit optical signals (214) and separates receive optical signals (216) to produce the multiple incoming signals (216a-216b). L'invention concerne un appareil (300) comprenant de multiples guides d'ondes à double gaine (222, 240) ayant chacun une section intérieure monomodale (220, 230) qui transporte l'un de multiples signaux optiques sortants et une section multimode (228, 238) entourant au moins partiellement la section intérieure (220, 230) qui transporte l'un de multiples signaux optiques entrants (216a-216b). Différents signaux sortants (214a-214b) ont des polarisations différentes, et différents signaux entrants (216a-216b) ont des polarisations différentes. L'appareil comprend également un diviseur de faisceau de polarisation (206) qui combine les multiples signaux sortants (214a-214b) pour produire des signaux optiques d'émission (214) et sépare des signaux optiques de réception (216) pour produire les multiples signaux entrants (216a-216b).
