Abstract

UN DISPOSITIVO OPTICO SEMICONDUCTOR, POR EJEMPLO UN LASER, TIENE UNA GUIA DE ONDAS OPTICA COMPUESTA, QUE COMPRENDE UNA GUIA DE ONDAS ACTIVA, CONICA, MQW (1), EN CONTACTO OPTICO CON UNA GUIA DE ONDAS PASIVA, SUBSTANCIALMENTE PLANA (2). EL MODO OPTICO FUNDAMENTAL SOPORTADO POR LA GUIA DE ONDAS COMPUESTA VARIA A LO LARGO DE LA LONGITUD DE LA GUIA DE ONDAS COMPUESTA DE MANERA QUE, EN UN LASER, EL MODO DEL LASER SE AGRANDA Y ENCAJA MEJOR CON UNA FIBRA OPTICA DE MODO SIMPLE. TAMBIEN SE PRESENTA UN METODO PARA HACER LOS DISPOSITIVOS OPTICOS SEMICONDUCTORES.
