Análisis comparativo de la transmitancia espectral para lentes filtrantes de baja visión
(Universitat Politècnica de Catalunya, 2017-10-25)
Projecte Final de Màster Oficial
Accés obertEn la pràctica diària dels optometristes especialitzats en baixa visió, és habitual l’ús de lents filtrants, més conegudes com filtres terapèutics. A Espanya, trobem diverses opcions comercials per poder adquirir aquest ... -
Control and enhancement of beam quality of broadarea semiconductor devices and arrays by multimode interference couplers and two-dimensional gain modulation
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
Text en actes de congrés
Accés obertIt is proposed to control the beam quality of broad-area semiconductor devices by two-dimensional structuring enforcing phase coherence across the device. First results based on MMI couplers are presented. -
