Broadband microwave photonic fully tunable filter using a single heterogeneously integrated III-V/SOI-microdisk-based phase shifter

Lloret Soler, Juan Antonio; Morthier, Geert; Ramos Pascual, Francisco; Sales Maicas, Salvador; Van Thourhout, D.; Spuesens, T.; Olivier, N.; Fedeli, J.M.; Capmany Francoy, José (Optical Society of America, 2012)

A broadband microwave photonic phase shifter based on a single III-V microdisk resonator heterogeneously integrated on and coupled to a nanophotonic silicon-on-insulator waveguide is reported. The phase shift tunability ...
Figures of merit for microwave photonic phase shifters based on semiconductor optical amplifiers

Sancho Durá, Juan; Lloret Soler, Juan Antonio; Gasulla Mestre, Ivana; Sales Maicas, Salvador; Capmany Francoy, José (Optical Society of America, 2012)

[EN] We theoretically and experimentally compare the performance of two fully tunable phase shifter structures based on semiconductor optical amplifiers (SOA) by means of several figures of merit common to microwave photonic ...
Silicon graphene waveguide tunable broadband microwave photonics phase shifter

Capmany Francoy, José; Doménech Gómez, José David; Muñoz Muñoz, Pascual (Optical Society of America: Open Access Journals, 2014-04-07)

We propose the use of silicon graphene waveguides to implement a tunable broadband microwave photonics phase shifter based on integrated ring cavities. Numerical computation results show the feasibility for broadband ...
Tunable and reconfigurable multi-tap microwave photonic filter based on dynamic Brillouin gratings in fibers

Sancho Durá, Juan; Sales Maicas, Salvador; Primerov, N.; Chin, S.; Antman, Y.; Zadok, A; Thevenaz, L. (Optical Society of America, 2012)

We propose and experimentally demonstrate new architectures to realize multi-tap microwave photonic filters, based on the generation of a single or multiple dynamic Brillouin gratings in polarization maintaining fibers. ...
Tunable complex-valued multi-tap microwave photonic filter based on single silicon-on-insulator microring resonator

Lloret Soler, Juan Antonio; Sancho Durá, Juan; Pu, M.; Gasulla Mestre, Ivana; Yvind, K.; Sales Maicas, Salvador; Capmany Francoy, José (Optical Society of America, 2011)

A complex-valued multi-tap tunable microwave photonic filter based on single silicon-on-insulator microring resonator is presented. The degree of tunability of the approach involving two, three and four taps is theoretical ...
