Compact and highly-efficient polarization independent vertical resonant couplers for active-passive monolithic integration
Galarza Galarza, Marko
; Thourhout, Dries Van; Baets, Roel; López-Amo Sáinz, Manuel (Optical Society of America, 2008)
Artículo / Artikulua 
Compact low-loss polarization independent vertical coupling between a 1.55 μm InGaAsP bulk active waveguide and a passive waveguide based on bimodal interference is presented. Simulation results show low coupling loss (<0.1 ... -
Diseño y caracterización de reflectores incoherentes de retrodispersión de fibra microperforada para láseres random de fibra óptica
Galarza Galarza, Marko ; Sañudo-Lasagabaster, Silvia; Pérez Herrera, Rosa Ana ; Roldán Varona, Pablo; Rodríguez Cobo, Luis; López Higuera, José Miguel; López-Amo Sáinz, Manuel (SEDOPTICA, 2021)
Contribución a congreso / Biltzarrerako ekarpena
Los láseres random de fibra óptica presentan una serie de características que los hacen idóneos para una gran variedad de aplicaciones industriales. La elevada longitud de fibra necesaria en la cavidad debido a sus bajos ... -
High sensitivity fiber-optic liquid level sensor using biconical tapered fibers
Júdez Colorado, Aitor; Leandro González, Daniel ; Pérez Herrera, Rosa Ana ; Galarza Galarza, Marko ; López-Amo Sáinz, Manuel (Optical Society of America, 2018)
Contribución a congreso / Biltzarrerako ekarpena
A liquid level sensor is presented using a biconical tapered standard single-mode fiber, being its main characteristic an outstanding sensitivity for a low cost transducer. Temperature compensation is enabled with the same ... -
Highly-efficient fully resonant vertical couplers for InP active-passive monolithic integration using vertically phase matched waveguides
García López, Óscar; Lasaosa Medarde, Daniel; López-Amo Sáinz, Manuel ; Galarza Galarza, Marko (Optical Society of America, 2013)
Artículo / Artikulua
A new active-passive monolithic integration approach for photonic components based on vertical evanescent coupling is presented. Two vertically stacked waveguides are used in order to provide full resonant power transfer ... -
