Resumen

En este artículo, un novedoso conversor modal basado en una fibra de cristal fotónico con núcleos asimétricos es propuesto y analizado a través de la implementación del método de elementos finitos. Este dispositivo permite la conversión modal entre los modos LP01 con el LP11 y LP01 con el LP21 a una longitud de onda de 1.55 µm. Adicionalmente, hemos encontrado que la longitud de onda de operación de este tipo de dispositivos presenta una fuerte dependencia con los parámetros geométricos de la estructura tales como el diámetro de los agujeros y la distancia entre ellos. Finalmente, se obtuvo un dispositivo fotónico compacto que puede ser empleado en las bandas O + S + C + L + U con eficiencias superiores al 80 % y una longitud total de 2 mm. Esta es una alternativa interesante a la hora de fabricar nuevos dispositivos totalmente integrados a fibra óptica que puedan ser implementados en sistemas de multiplexación por división modal.
